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

You are watching: Twice the sum of a number

In various other words, the three main components 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 instances that can help you acquire familiarized v the work of addition, subtraction, multiplication,and division.

Addition

the amount of x and also 5 → x+5

Subtraction

the distinction of y and also 3 → y-3

Multiplication

the product of n and 2 → 2n

Division

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

Writing Algebraic expression Step-by-Step examples

Let’s walk over much more examples.

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

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

Example 2: The distinction of triple a number and 5

Answer:Let change y be the unknown number. So triple a number way 3y. The difference (use minus symbol) the triple a number and also 5 have to be created as 3y - 5.

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

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

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

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

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

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

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

The key is to identify that we room going to subtract the product through the quotient of part expressions.

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

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