Operators

In computer science, an is a character, or characters that determine the action that is to be performed or considered.

There are three types of operator that programmers use:

Computers are designed to carry out calculations. Mathematical operators allow arithmetic to be performed on values.

Mathematical operation	Operator	Example
Addition	`+`	`x = x + 5`
Subtraction	`-`	`x = x - 5`
Multiplication	`*`	`x = x * 5`
Division	`/`	`x = x / 5`
Integer division	`DIV` (finds the whole number after the division)	`x = x DIV 5` If `x` is 21, then the result of this is that `x` is 4
Remainder	`MOD` (finds the remainder after the modulus division)	`x = x MOD 5` If `x` is 21, then the result of this is that `x` is 1

Example

x = x DIV 5

If

Operator	`MOD` (finds the remainder after the modulus division)
Example	`x = x MOD 5` If `x` is 21, then the result of this is that `x` is 1

MOD

(finds the remainder after the modulus division)

Example

x = x MOD 5

If

is 21, then the result of this is that

is 1

Logical operators allow for and for comparisons to be made. They are used in testing.
