# Operand

In mathematics, an operand is a number or variable being worked on in an equation or inequality. In ${\displaystyle 1+2}$, the operands are ${\displaystyle 1}$ and ${\displaystyle 2}$, and the operator is ${\displaystyle +}$.

## Notation

In ${\displaystyle (3+5)\times 2}$, the operands are 3, 5 and 2, and the operators are ${\displaystyle +}$ and ${\displaystyle \times }$.

## Name of operands

${\displaystyle +}$ Addition: addend

${\displaystyle -}$ Subtraction: minuend & subtrahend

${\displaystyle \times }$ Multiplication: factor

${\displaystyle /}$ Division: dividend & divisor

${\displaystyle x^{y}}$ Exponentiation: base & exponent

${\displaystyle {\sqrt {x}}}$ Root: index & radicand

${\displaystyle \log({x})}$ Logarithm: base & power

\ Modulation: modulend & modulator

${\displaystyle n!}$ Factorial: index

${\displaystyle \sum _{k}^{n}{x}}$ Summation: summand

${\displaystyle \prod _{k}^{n}{x}}$ Product: multiplicand

${\displaystyle \lim _{k\to n}{x}}$ Limit: index & limit

${\displaystyle \lfloor x\rceil }$ Nearest integer: index

${\displaystyle \lfloor x\rfloor }$ Floor: index

${\displaystyle \lceil x\rceil }$ Ceiling: index

${\displaystyle [x]}$ Integer part: index
