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**.

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

Variables or LettersExamples:x, y, a, h, p, etc.

Arithmetic OperationsExamples:+ (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.

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.

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