What is Arithmetic? – Definition, Facts & Examples

A series is the total of a succession of events. We’re looking for the n th partial sum, which is the sum of the first n terms in the series of terms. The n thparticipant sum shall be denoted by the letter S n. Consider the arithmetic series as an example. S 5= 2 + 5 + 8 + 11 + 14 = S 5 = 2 + 5 + 8 + 11 + 14 = S 5 There is a straightforward method for calculating the sum of an arithmetic series. The number S 5 is made up of the numbers 2-5-8-11-14. The trick is to change the order of the terms in the sentence.

S 5 = 14 + 11 + 8 + 5 + 2 = 14 + 11 + 8 + 5 + 2 = S 5 Now, combine the two equations together to get the final result.

Instead of writing 16 (the sum of the first and last terms) five times, we may write it as 5 * 16 or 5 * (2 + 14), which is the same as 5 * 16 or 5 * (2 + 14).

S 5 = 5/2 * (2 + 14) = S 5.

  1. This would be 5/2 * (16) = 5(8) = 40, which is the total.
  2. The number 5 represents the fact that there were five terms, n.
  3. Since we added the total twice, it will always be a 2, which is the sum of the first n terms in an arithmetic series.
  4. It is derived by putting the formula for the general term into the previous formula and simplifying the result.
  5. In this case, S = n/2 * (2a 1+ (n-1) d)
  • The process of taking two or more numbers and adding them together is referred to as the addition. Or to put it another way, it is the entire sum of all the numbers. The addition of whole numbers results in a number that is bigger than the sum of the numbers that were added.

The process of taking two or more numbers and adding them together is referred to as addition. To put it another way, it is the entire sum of all the figures. It is possible to have a number higher than the sum of two whole numbers; however, this is not the case.

  • Subtraction is the technique through which we remove things from a group that they were previously part of. When a number is subtracted from another number, the numerical value of the original number decreases.

For example, eight birds are perched on a branch of a tree. After a while, two birds take off in different directions. What is the number of birds on the tree? As a result, there are only 6 birds remaining on the tree after subtracting 8 from 2. Multiplication:

  • Multiplication is defined as the process of adding the same integer to itself a certain number of times. When two numbers are multiplied together, the result is referred to as a product.

Consider the following scenario: Robin went to the garden three times and returned back five oranges each time. What was the total number of oranges Robin brought? Robin went to the garden three times to find a solution. He showed up with five oranges every time. This may be expressed numerically as 5 x 3 = 15 oranges, for example. Division:

  • Divide and conquer is the process of breaking down a huge thing or group into smaller portions or groupings. Generally speaking, the dividend refers to the number or bigger group that is divided. The dividend is divided by a number, which is referred to as the divisor. In mathematics, thequotient is the number derived by multiplying the dividend by a divisor. The number that is left over after dividing is referred to as the remnant.

For example, when 26 strawberries are distributed among 6 children, each child receives 4 strawberries, leaving 2 strawberries behind. Fascinating Facts

Arithmetic Sequence

An Arithmetic Sequence is characterized by the fact that the difference between one term and the next is a constant. In other words, we just increase the value by the same amount each time. endlessly.

Example:

1, 4, 7, 10, 13, 16, 19, 22, and 25 are the numbers 1 through 25. Each number in this series has a three-digit gap between them. Each time the pattern is repeated, the last number is increased by three, as seen below: As a general rule, we could write an arithmetic series along the lines of

  • There are two words: Ais the first term, and dis is the difference between the two terms (sometimes known as the “common difference”).

Example: (continued)

1, 4, 7, 10, 13, 16, 19, 22, and 25 are the numbers 1 through 25. Has:

  • In this equation, A = 1 represents the first term, while d = 3 represents the “common difference” between terms.

And this is what we get:

Rule

It is possible to define an Arithmetic Sequence as a rule:x n= a + d(n1) (We use “n1” since it is not used in the first term of the sequence).

Example: Write a rule, and calculate the 9th term, for this Arithmetic Sequence:

3, 8, 13, 18, 23, 28, 33, and 38 are the numbers three, eight, thirteen, and eighteen. Each number in this sequence has a five-point gap between them. The values ofaanddare as follows:

  • A = 3 (the first term)
  • D = 5 (the “common difference”)
  • A = 3 (the first term).

Making use of the Arithmetic Sequencerule, we can see that_xn= a + d(n1)= 3 + 5(n1)= 3 + 3 + 5n 5 = 5n 2 xn= a + d(n1) = 3 + 3 + 3 + 5n n= 3 + 3 + 3 As a result, the ninth term is:x 9= 5 9 2= 43 Is that what you’re saying? Take a look for yourself! Arithmetic Sequences (also known as Arithmetic Progressions (A.P.’s)) are a type of arithmetic progression.

  • In this equation, A = 1 represents the first term, d = 3 represents the “common difference” between terms, and n = 10 represents the number of terms to add up.

As a result, the equation becomes:= 5(2+93) = 5(29) = 145 Check it out yourself: why don’t you sum up all of the phrases and see whether it comes out to 145?

Footnote: Why Does the Formula Work?

As a result, 5(2+93) = 5(29) = 145 is obtained. Take a look at it yourself: why don’t you sum up the phrases and check whether it comes out to 145?

S = a + (a+d) + . + (a + (n-2)d) + (a + (n-1)d)
S = (a + (n-1)d) + (a + (n-2)d) + . + (a + d) + a
2S = (2a + (n-1)d) + (2a + (n-1)d) + . + (2a + (n-1)d) + (2a + (n-1)d)

Each and every term is the same! Furthermore, there are “n” of them. 2S = n (2a + (n1)d) = n (2a + (n1)d) Now, we can simply divide by two to obtain the following result: The function S = (n/2) (2a + (n1)d) is defined as This is the formula we’ve come up with:

Lesson Plan

Mathematical arithmetic is a field of mathematics in which we study numbers and relationships between numbers by examining their properties and using them to solve instances. Mathematical operations are sprung from the Greek term “arithmos,” which means “numbers.” Mathematical arithmetic is one of the oldest and most fundamental foundations of mathematics. It is concerned with numbers and the simple operations (addition, subtraction, multiplication, and division) that can be done on those numbers in order to solve problems.

Basic Rules of Arithmetic

Let’s take a quick look at the most fundamental arithmetic operations.

Addition and Subtraction

The arithmetic operations of addition and subtraction are the most fundamental. All of these notions serve as building blocks for comprehending and functioning on numerical data. In our daily lives, we add and subtract numbers, quantities, and values of many kinds. As a visual representation, addition may be thought of as the ‘combining’ of two or more quantities. Subtraction is a mathematical term that refers to the process of taking something away from a set of objects. In other terms, subtraction is the process of deleting items from a collection.

Multiplication and Division

Arithmetic operations such as multiplication and division are among the four fundamental arithmetic operations that may be used to a variety of mathematical concepts such as multiplying and dividing fractions, decimals, rationals, integers, and so on. These operations serve as the fundamental building blocks for all other mathematical notions. Finally, division is included in the list of fundamental arithmetic operations. In layman’s terms, division may be defined as the division of a large group into equal smaller groups by dividing them into equal smaller groups.

Equal to Sign: “=”

The equal to sign is used to express the outcome of operations on integers, and it may be read as

Inverse Operations

  • When it comes to operations, addition and subtraction are inverse operators of one another. In a similar vein, the operations multiplication and division are the inverse operators of one another.

Example 1

When we multiply 3 by 8, we obtain the number 11. for example, 8+3 = 11 This would also imply the following:

  • If we subtract three from eleven, we get eight
  • If we subtract eight from eleven, we get three.

Example 2

The number 24 is obtained by multiplying 3 by 8, i.e. 8 x 3 = 24. This would also imply the following:

  • Divide 24 by 3 and you get 8
  • Divide 24 by 8 and you get 3
  • Divide 24 by 3 and you get 3.

Divide 24 by 3 and you get 8; divide 24 by 8 and you get 3; divide 24 by 3 and you get 8.

Arithmetic Examples

Let’s look at a few math examples from our everyday lives to get started.

Example 1

The flowers were collected by Sia from a garden and given evenly to nine of her acquaintances. Can you figure out how many bouquets of flowers each of her pals received? Because we need to distribute 45 flowers evenly among 9 children, we must divide 45 by 9 to arrive at a solution. As a result, everyone of her pals will get five bouquets of flowers.

Example 2

John and Mia each received four packets of candy from their mother. Each package included a total of 5 candy pieces. Can you figure out how many candies there were in total? The number of candies contained in a single package is five.

As a result, the quantity of candies in four packets is equal to (four times five equals twenty). As a result, each youngster will receive a total of 20 sweets. The number of children is two. As a result, the total number of candies is equal to (20 times 2=40).

  1. Arithmetic is a discipline of mathematics that deals with the manipulation of numbers
  2. It is also known as number theory. Addition, subtraction, multiplication, and division are the four fundamental operations of arithmetic, respectively. The DMAS rule specifies the sequence in which these operations must be performed.

Arithmetic Sequence – Formula, Meaning, Examples

When you have a succession of integers where the differences between every two subsequent numbers are the same, you have an arithmetic sequence. Let us take a moment to review what a sequence is. A sequence is a set of integers that are arranged in a certain manner. An arithmetic sequence is defined as follows: 1, 6, 11, 16,. is an arithmetic sequence because it follows a pattern in which each number is acquired by adding 5 to the phrase before it. There are two arithmetic sequence formulae available.

What is an Arithmetic Sequence?

There are two ways in which anarithmetic sequence can be defined. When the differences between every two succeeding words are the same, it is said to be in sequence (or) Every term in an arithmetic series is generated by adding a specified integer (either positive or negative, or zero) to the term before it. Here is an example of an arithmetic sequence.

Arithmetic Sequences Example

There are two approaches to define anarithmetic sequence. It is a series in which the differences between every two consecutive words are the same as one another (or) Arithmetic sequences are formed by adding a specified number (either positive or negative) to each phrase in the series that precedes it. Here’s an example of an arithmetic sequence:

  • A = 3 for the first term
  • D = 6 – 3 for the common difference
  • 12 – 9 for the second term
  • 15 – 12 for the third term
  • A = 3 for the third term

As a result, arithmetic sequences can be expressed as a, a + d, a + 2d, a + 3d, and so forth. Let’s use the previous scenario as an example of how to test this pattern. a, a + d, a + 2d, a + 3d, a + 4d,. = 3, 3 + 3, 3 + 2(3), 3 + 3(3), 3 + 4(3),. = 3, 6, 9, 12, 15,. = 3, 6, 9, 12, 15,. = 3, 6, 9, 12, 15,. = 3, 6, 9, 12, 15,. Here are a few more instances of arithmetic sequences to consider:

  • 5, 8, 11, 14,
  • 80, 75, 70, 65, 60,
  • 2/2, 3/2, 2/2,
  • -2, -22, -32, -42,
  • 5/8, 11/14,

The terms of an arithmetic sequence are often symbolized by the letters a1, a2, a3, and so on.

Arithmetic sequences are discussed in the following way, according to the vocabulary we employ.

First Term of Arithmetic Sequence

The first term of an arithmetic sequence is, as the name implies, the first integer in the sequence. It is often symbolized by the letters a1 (or) a. For example, the first word in the sequence 5, 8, 11, 14, is the number 5. Specifically, a1 = 6 (or) a = 6.

Common Difference of Arithmetic Sequence

The addition of a fixed number to each preceding term in an arithmetic series, with one exception (the first term), has previously been demonstrated in prior sections. The “fixed number” in this case is referred to as the “common difference,” and it is symbolized by the letter d. The formula for the common difference isd = a – an1.

Nth Term of Arithmetic Sequence Formula

In such case, the thterm of an arithmetic series of the form A1, A2, A3,. is given byan = a1 + (n-1) d. This is also referred to as the broad word for the arithmetic sequence in some circles. This comes immediately from the notion that the arithmetic sequence a1, a2, a3,. = a1, a1 + d, a1 + 2d, a1 + 3d,. = a1, a1 + d, a1 + 3d,. = a1, a1 + 3d,. = a1, a1 + 3d,. Several arithmetic sequences are shown in the following table, along with the first term, the common difference, and the subsequent n thterms.

Arithmetic sequence First Term(a) Common Difference(d) n thtermaₙ = a₁ + (n – 1) d
80, 75, 70, 65, 60,. 80 -5 80 + (n – 1) (-5)= -5n + 85
π/2, π, 3π/2, 2π,. π/2 π/2 π/2 + (n – 1) (π/2)= nπ/2
-√2, -2√2, -3√2, -4√2,. -√2 -√2 -√2 + (n – 1) (-√2)= -√2 n

Arithmetic Sequence Recursive Formula

It is possible to utilize the following formula for finding the nthterm of an arithmetic series in order to discover any term of that sequence if the values of ‘a1′ and’d’ are known, however this is not recommended. One further method of determining what term is the n thterm is to utilize the ” recursive formula of an arithmetic sequence “. This formula may be used to determine the next term (an) of an arithmetic sequence given both its preceding term (an1) and the value of the variable ‘d’ are known.

Example: If a19 = -72 and d = 7, find the value of a21 in an arithmetic sequence.

a21 = a20 + d = -65 + 7 = -58; a21 = a20 + d = -65 + 7 = -58; a21 = a20 + d = -65 + 7 = -58; As a result, the value of a21 is -58.

Sum of Arithmetic sequence Formula

To obtain the sum of the first n terms of an arithmetic sequence, the sum of the arithmetic sequence formula is employed. Consider the following arithmetic sequence: a1 (or ‘a’) is the first term, and d is the common difference between the first and second terms. Sn is the symbol for the sum of the first n terms in the expression. Then

  • The following is true: When the n thterm is unknown, Sn= n/2
  • When the n thterm is known, Sn= n/2

Example Ms. Natalie makes $200,000 each year, with an annual pay rise of $25,000 in addition to that. So, how much money does she have at the conclusion of the first five years of her career? Solution In Ms. Natalie’s first year of employment, she earns a sum equal to a = 2,000,000. The annual increase is denoted by the symbol d = 25,000. We need to figure out how much money she will make in the first five years. As a result, n = 5. In the sum sum of arithmetic sequence formula, substituting these numbers results in Sn = n/2 Sn = 5/2(2(200000) + (5 – 1)(25000), which is 5/2 (400000 +100000), which is equal to 5/2 (500000), which is equal to 1250000.

In five years, she makes a total of $1,250,000. We may modify this formula to be more useful for greater values of the constant ‘n.’

Sum of Arithmetic Sequence Proof

Consider the following arithmetic sequence: a1 is the first term, and d is the common difference between the two terms. The sum of the first ‘n’ terms of the series is given bySn = a1 + (a1 + d) + (a1 + 2d) +. + an, where Sn = a1 + (a1 + d) + (a1 + 2d) +. + an. (1) Let us write the same total from right to left in the same manner (i.e., from the n thterm to the first term). (an – d) + (an – 2d) +. + a1. Sn = a plus (an – d) plus (an – 2d) +. + a1. (2)By combining (1) and (2), all words beginning with the letter ‘d’ are eliminated.

+ (a1 + an) 2Sn = n (a1 + an) = n (a1 + an) Sn =/2 is a mathematical expression.

Arithmetic Sequence Formulas

The following are the formulae that are connected to the arithmetic sequence.

  • There is a common distinction, the n-th phrase, a = (a + 1)d
  • The sum of n terms, Sn =/2 (or) n/2 (2a + 1)d
  • The n-th term, a = (a + 1)d
  • The n-th term, a = a + (n-1)d

FAQs on Arithmetic sequence

An arithmetic sequence is a sequence of integers in which every term (with the exception of the first term) is generated by adding a constant number to the preceding term. For example, the arithmetic sequence 1, 3, 5, 7, is an arithmetic sequence because each term is created by adding 2 (a constant integer) to the term before it.

What are Arithmetic Sequence Formulas?

Here are the formulae connected to an arithmetic series where a1 (or a) is the first term and d is the common difference: a1 (or a) is the first term, and d is the common difference:

  • Listed below are the formulae that are connected to an arithmetic sequence where a1 (or a) is the first term and d is the common difference: a1 (or a) is the first term and d is the common difference

How to Find An Arithmetic Sequence?

Arithmetic Mean Definition

It is the simplest and most generally used measure of amean, or average, since it is the most straightforward to calculate. It is as simple as taking the total of a set of numbers and dividing that sum by the amount of numbers that were used in the series to arrive at the answer. Let’s say you have the numbers 34, 44, 56, and 78 on your hands. The total comes to 212. The arithmetic mean is equal to 212 divided by four, which equals 53. Additionally, people employ a variety of different sorts of means, such as thegeometric mean and theharmonic mean, which come into play in a variety of scenarios in finance and investment.

Key Takeaways

  • It is the simplest and most generally used measure of amean, or average, since it is so straightforward and straightforward to calculate. It is as simple as taking the total of a group of numbers and dividing that sum by the amount of numbers that were used in the series to arrive at the solution. Consider the digits 34, 44, 56, and 78, as an example. 212 is the answer. It is equal to 212 divided by four, which is 53 as an arithmetic mean Apart from the geometric mean and harmonic mean, people utilize a variety of different forms of means, which are useful in finance and investment when particular scenarios arise. For instance, when computing economic statistics such as the consumer price index (CPI) and personal consumption expenditures, the trimmed mean is employed (PCE).

How the Arithmetic Mean Works

The arithmetic mean retains its significance in the field of finance as well. To give an example, mean earnings predictions are often calculated using the arithmetic mean. Consider the following scenario: you want to know the average earnings projection of the 16 analysts covering a specific stock. To find the arithmetic mean, just add up all of the estimations and divide the total by 16. The same is true if you wish to figure out what a stock’s average closing price was for a specific month.

To find the arithmetic mean, just add up all of the costs and divide by 23 to arrive at the final figure.

As a measure of central tendency, it’s also valuable because it tends to produce relevant findings even when dealing with big groupings of numbers.

Limitations of the Arithmetic Mean

The arithmetic mean isn’t always the best choice, especially when a single outlier has the potential to significantly distort the mean. Consider the following scenario: you need to estimate the allowance for a group of ten children. Nine of them are given a weekly stipend ranging between $10 and $12. The tenth child is entitled to a $60 stipend. Because of that one outlier, the arithmetic mean will be $16, not $16 + $1. This is not a particularly representative sample of the group. In this specific instance, the medianallowance of ten points could be a more appropriate metric.

It is also not commonly utilized to compute present and future cash flows, which are employed by analysts in the preparation of their forecasts. It is almost certain that doing so will result in erroneous data.

Important

When there are outliers or when looking at past returns, the arithmetic mean might be deceiving to the investor. In the case of series that display serial correlation, the geometric mean is the most appropriate choice. This is particularly true in the case of investment portfolios.

Arithmetic vs. Geometric Mean

The geometric mean, which is determined in a different way, is frequently used in these applications by analysts. When dealing with series that demonstrate serial correlation, the geometric mean is the most appropriate choice. This is particularly true in the case of investment portfolios. The majority of returns in finance are connected, including bond yields, stock returns, and market risk premiums, among other things. Because of this, the use of crucial compounding and the geometric mean becomes increasingly important as the time horizon grows.

Taking the product of all the numbers in the series, the geometric mean increases it by the inverse of the length of the series, yielding the geometric mean.

The geometric mean varies from the arithmetic mean in that it takes into consideration the compounding that occurs from one period to the next.

Example of the Arithmetic vs. Geometric Mean

Suppose the returns on an investment during the previous five years were 20 percent, 6 percent, 10 percent, -1 percent, and 6 percent, respectively. The arithmetic mean would simply put them all together and divide by five, yielding an annualized rate of return of 4.2 percent on average. The geometric mean, on the other hand, would be computed as (1.2 x 1.06 x 0.9 x 0.99 x 1.06) 1/5-1 = 3.74 percent per year average return on the investment. It is important to note that the geometric mean, which is a more accurate computation in this circumstance, will always be less than the arithmetic mean in this situation.

What is Arithmetic? Definition, Basic Operations, Examples

At the time, arithmetic was most likely the subject with the longest history. Historically, it has been used for everyday calculations such as measurements, labeling, and other day-to-day computations to get exact results, and it has been used from the beginning of time. The word “arithmos” comes from the Greek word “arithmos,” which literally translates as “numbers.” In mathematics, arithmetic is the foundational topic that examines numbers and the features of ordinary operations such as addition, subtraction, multiplication, and division.

Arithmetic is a branch of mathematics that deals with numbers and the operations that may be performed on them.

Basic Operations of Arithmetic

According to the statement, there are four fundamental operations in arithmetic that are utilized to do calculations: (+) is used to indicate an addition. Simple description of addition will be that it is an operation that combines two or more values or numbers to form a single value or value set. Summation is the term used to describe the process of adding n numbers of values together.

  • In mathematics, the number zero is referred to be the identity element of addition since adding zero to every value produces the same result. Example: If we add 0 to 7, the outcome is the same as if we subtract 0 from 7: 7.
  • In addition, the inverse element contains the addition of the value that is the inverse of the current value. An identity element with value zero will be produced as a result of combining inverse elements. For example, if we multiply 4 by its inverse value, -4, the outcome is as follows:

4 plus (-4) equals 0 Subtraction is a mathematical operation (-) In mathematics, subtraction is the arithmetic operation that is used to compute the difference between two different numbers (i.e. minuend minus the subtrahend).

  • It is possible to have a positive difference in the circumstance where the minuend is bigger than the subtrahend. It is the inverse of the operation of addition.
  • In contrast, if the subtrahend is bigger than the minuend, the difference between the two will be negative
  • And

2 – 4 = -2 is a negative number.

Multiplication () is a mathematical operation. Known as multiplicand and multiplier, they are the two values that are involved in the action of multiplication. In order to produce a single product, it combines two values that are multiplicand and multiplier.

  • This form is used to describe the product of two values that are purportedly p and q
  • The product of two values that are supposedly q is stated in the p.q or pq form.

5 x 6 = 30Division (division) The division operation is the one that is used to get the quotient of two integers. It is the inverse of the operation of multiplication.

  • In this case, the two numbers involved in it are referred to as dividends by the divisor, and if the quotient is more than 1, and if the dividend is larger than or equal to the divisor, the outcome is a positive number
  • Otherwise, it is a negative number.

12 divided by 3 equals 4.

What is an arithmetic sequence? + Example

An arithmetic sequence is a series (list of numbers) in which there is a common difference (a positive or negative constant) between the items that are consecutively listed. For example, consider the following instances of arithmetic sequences: 1.) The numbers 7, 14, 21, and 28 are used because the common difference is 7. 2.) The numbers 48, 45, 42, and 39 are chosen because they have a common difference of – 3. The following are instances of arithmetic sequences that are not to be confused with them: It is not 2,4,8,16 since the difference between the first and second terms is 2, but the difference between the second and third terms is 4, and the difference between the third and fourth terms is 8 because the difference between the first and second terms is 2.

2.) The numbers 1, 4, 9, and 16 are incorrect because the difference between the first and second is 3, the difference between the second and third is 5, and the difference between the third and fourth is 7.

The reasons for this are that the difference between the first and second is three points, the difference between the second and third is two points, and the difference between third and fourth is five points. There is no common difference between the numbers, hence it is not an arithmetic sequence.

Arithmetic Operators – Programming Fundamentals

An arithmetic sequence is a series (list of numbers) in which there is a common difference (either a positive or negative constant) between the words that are successive. Some instances of arithmetic sequences include the following: 1.) The numbers 7, 14, 21, and 28 are chosen because the common difference is seven. 2.) Secondly, the numbers 48, 45, 42, and 39 are chosen because they all have a – 3. Arithmetic sequences do not include the following examples: It is not 2,4,8,16 since the difference between the first and second terms is 2, but the difference between the second and third terms is 4, and the difference between the third and fourth terms is 8 because the difference between the first and second terms is 2.

2.) The numbers 1, 4, 9, and 16 are incorrect since the difference between the first and second is 3, the difference between the second and third is 5, and the difference between the third and fourth is seven.

Because the difference between the first and second is 3, the difference between third and fourth is 2, and the difference between fifth and tenth is twelve, the numbers 2, 5, 7, and 12 are not valid.

Discussion

Operands are used to conduct actions on one or more operands, which are called operators. The following are the most frequently used arithmetic operators:

Action Common Symbol
Addition +
Subtraction
Multiplication *
Division /
Modulus (associated with integers) %

These arithmetic operators are binary, which means that they have just two operands to work with. There are two types of operands: constants and variables. age multiplied by one This expression is made up of one operator (addition), which has two operands, and one variable. First, a variable named age is used to represent the first, while the second is represented by a literal constant named age2. If age had a value of 14, the expression would evaluate to (or be equal to) 15 if the age value was 14.

Most of the time, we conceive about division as resulting in an answer that may have a fractional component (a floating-point data type).

Please see the following section on “Integer Division and Modulus” for further information.

Arithmetic Assignment Operators

Many programming languages allow you to use the assignment operator (=) in conjunction with the arithmetic operators (+,-,*,/, percent). They are referred to as “compound assignment operators” or “combined assignment operators” in several textbooks.

These operators’ functions may be stated in terms of the assignment operator and the arithmetic operators, respectively. We will utilize the variable age in the table, and you may presume that it is of the integer data type, which is correct.

Arithmetic assignment examples: Equivalent code:
age += 14; age = age + 14;
age -= 14; age = age – 14;
age *= 14; age = age * 14;
age /= 14; age = age / 14;
age %= 14; age = age % 14;
