As with any type of language, math has actually a way to interact concepts. An algebraic expression is a compact way of describing mathematical objects using a combination of numbers, variables (letters), and also arithmetic operationsnamely enhancement, subtractivity, multiplication, and also division.

You are watching: N divided by 8 in algebraic expression

In other words, the 3 main components of algebraic expressions are numbers, variables, and also arithmetic operations.

Numbers or Constants

Examples:1, 6, 8, 27, 32, and so on.

Variables or Letters

Examples:x, y, a, h, p, etc.

Arithmetic Operations

Examples:+ (addition), - (subtraction) , imes (multiplication) , ÷ (division)

The adhering to are basic examples that can aid you obtain familiarized with the operations of addition, subtraction, multiplication,and department.

Addition

the sum of x and also 5 → x+5

Subtraction

the distinction of y and also 3 → y-3

Multiplication

the product of n and also 2 → 2n

Division

the quotient of k and 7 → Largek over 7

Writing Algebraic Expressions Step-by-Step Examples

Let’s go over even more examples.

Example 1: The sum of twice a number and also 3

Answer: Let variable x be the unwell-known number. So twice a number implies 2x. The sum (usage plus symbol) of twice a number and 3 have the right to be composed as 2x+3.

Example 2: The distinction of triple a number and also 5

Answer:Let variable y be the unrecognized number. So triple a number suggests 3y. The difference (use minus symbol) of triple a number and 5 have to be written as 3y - 5.

Example 3:The sum of the quotient of m and also 2, and also the product of 4 and also n.

Answer:In this case, the unrecognized numbers are already provided as m and n. That’s one much less point to problem.

The crucial is to recognize that we are going to add a quotient and a product.

the quotient of m and also 2 is expressed as Largem over 2the product of 4 and also n is expressed as 4n

Thus, the sum of the quotient and product is Largem over 2 + 4n.

Example 4: The distinction of the productof 7 and also w, and also the quotient of 2 and v.

Answer: In this case, the unknown numbers have been assigned with equivalent variables which are w and v.

The vital is to recognize that we are going to subtract the product by the quotient of some expressions.

the product of 7 and also w is expressed as 7wthe quotient of 2 and also v is expressed as Large2 over v

Therefore, the distinction of the product and also quotient is 7w - Large2 over v.
