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

You are watching: Five less than the product of a number and 3 is 14

In various other words, the 3 main contents of algebraic expressions space numbers, variables, and also 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 assist you obtain familiarized through the operations of addition, subtraction, multiplication,and division.

the sum of x and also 5 → x+5

Subtraction

the difference of y and 3 → y-3

Multiplication

the product of n and 2 → 2n

Division

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

## Writing Algebraic expressions Step-by-Step examples

Let’s walk over an ext examples.

Example 1: The sum of twice a number and 3

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

Example 2: The difference of triple a number and 5

Answer:Let change y be the unknown number. Therefore triple a number method 3y. The difference (use minus symbol) of triple a number and also 5 need to be composed as 3y - 5.

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

Answer:In this case, the unknown numbers are already noted as m and n. That’s one much less thing to worry.

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

the quotient of m and 2 is expressed together \Largem \over 2the product of 4 and n is expressed together 4n

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

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

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

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

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

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