# Arithmetic/Introduction to Operations

From Wikibooks, open books for an open world

There are four basic *operators*, which are used to work with numbers for uses besides counting. They are:

- + addition
- - subtraction
- × multiplication (The symbol * is also used to multiply)
- ÷ division (The symbol / is also used to divide)

## Addition[edit]

Addition is the summation of two numbers. For example, 1 + 2 = 3.

## Subtraction[edit]

Subtraction is the opposite of addition. It is the taking away of one number from another. For example, 2 - 1 = 1

## Multiplication[edit]

Multiplication is the adding of a number a certain number of times. So 2 *1 = 2, 2 * 2 = 2 + 2 = 4, 2 * 3 = 2 + 2 + 2 = 6, etc.

## Division[edit]

Division is the splitting of a number into a number of equal parts. For example, 6 ÷ 2 = 3.
