# Operand

object of a mathematical operation, quantity on which an operation is performed

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

${\displaystyle \log({x})}$  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
