Operator

In mathematics, an operator is a function (like addition) that acts on one or more numbers to create a new number.

The most known operators are those used for the first four arithmetic operations: addition, subtraction, multiplication, and division ($+$, $-$, $\times$, $/$).

List of operators

• Addition: $+$
• Subtraction: $-$
• Multiplication: $\times$
• Division: $/$
• Division (fraction): $-$
• Exponentiation: $x^y$
• Root (radical): $\sqrt{}$
• Logarithm: $\log$
• Modulation: $\mathrm{\setminus }$
• Factorial: $!$
• Summation: $\sum$
• Product: $\prod$
• Limit: $\lim$
• Nearest integer: $\lfloor \rceil$
• Floor: $\lfloor \rfloor$
• Ceiling: $\lceil \rceil$
• Integer part: $[]$
• Fractional part: $\{\}$
