From Wikibooks, the open-content textbooks collection
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)

[edit] Addition
Addition is the combination of two numbers. For example, 1 + 2 = 3.
[edit] Subtraction
Subtraction is the opposite of addition. It is the taking away of one number from another. For example, 2 - 1 = 1
[edit] Multiplication
Multiplication is the adding of a number a certain number of times. So 2 * 3 = 2 + 2 = 4 + 2 = 6.
[edit] Division
Division is the splitting of a number into a number of equal parts. For example, 6 ÷ 2 = 3.
