# Operators

There are seven major types of mathematical operator, and four major types of bitwise operator.

## Mathematical operators

Operation Character used Description Example
Addition Performed using the "+" operator Adds values together. A + B = 12
Subtraction Performed using the "-" operator Subtracts values. A - B = 8
Multiplication Performed using the "*" operator Multiplies values together. A * B = 20
Division Performed using the "/" operator Divides values. S / B = 5
Increment Performed using the "++" operator Adds 1 to a variable and saves the variable. A++ = 11
Decrement Performed using the "--" operator Subtracts 1 from a variable and saves the variable. B-- = 9
Modulus Performed using the "%" operator Finds the remainder of a division between values. 10 % 3 = 1

Note: there are variations on the increment and decrement operators. These can be performed in both prefix and postfix forms. In prefix form, (syntax "++x;") the variable will be incremented or decremented, and then the value will be used by the function calling it. In postfix form, however, (syntax "x++;") the variable will be used by the function calling it, and be incremented or decremented afterwards.

## Comparison Operators

Operation Character used Description Example
Equal Performed using == Returns true if both inputs are the same. value == "test"
Not Equal performed using != returns true if both inputs are not the same value != "test"
Less Than Performed using < Returns true if value 1 is less than or equal to value 2. value < 0
Greater Than performed using > Returns true if value 1 is greater than value 2. value > 1
Less Than or Equal Performed using <= Returns true if value 1 is less than or equal to value 2. value <= 0
Greater Than or Equal performed using >= Returns true if value 1 is greater than or equal to value 2. value >= 1

## Bitwise operators

Operation Character used Description Example
AND Performed using "&" or "&&" Returns true if both inputs are true. true && false = false
OR performed using "|" or "||" returns true if one or both inputs are true. true || false = true
XOR Performed using "^" Returns true if both inputs are different. true ^ false = true
NOT performed using "!" Returns false if true, or true if false. !true = false

The "and" and "or" operators also have variants when combined with "not", known as "nand" and "nor", but these cannot be performed directly in C#. and instead must be performed by combining the "and"/"or" with the "not" function.
