Just like any type of language, math has a method to interact ideas. One algebraic expression is a compact method of explicate mathematical objects using a combination the numbers, variables (letters), and arithmetic operationsnamely addition, subtraction, multiplication, and also division.

You are watching: 9 less than the quotient of n and 5

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

Numbers or Constants

Examples:1, 6, 8, 27, 32, etc.

Variables or Letters

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

Arithmetic Operations

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

The complying with are easy examples that can aid you acquire familiarized through the operations of addition, subtraction, multiplication,and division.


the amount of x and 5 → x+5


the difference of y and also 3 → y-3


the product of n and also 2 → 2n


the quotient the k and also 7 → \\Largek \\over 7

Writing Algebraic expressions Step-by-Step examples

Let’s go over more examples.

Example 1: The sum of double a number and 3

Answer: Let change x be the unknown number. So twice a number method 2x. The amount (use add to symbol) of double a number and 3 have the right to be composed as 2x+3.

Example 2: The difference of triple a number and 5

Answer:Let variable y be the unknown number. For this reason triple a number method 3y. The difference (use minus symbol) that triple a number and also 5 have to be written as 3y - 5.

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

Answer:In this case, the unknown numbers room already provided as m and also n. That’s one less thing to worry.

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

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

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

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

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

The an essential is to acknowledge that we are going to subtract the product by the quotient of part expressions.

the product that 7 and w is expressed together 7wthe quotient that 2 and v is expressed as \\Large2 \\over v

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