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.

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

Operands have different names depending on the operation that is done to them.

• ${\displaystyle x+y}$  Addition: addend
• ${\displaystyle x-y}$  Subtraction: minuend & subtrahend
• ${\displaystyle x\times y}$  Multiplication: factor
• ${\displaystyle x/y}$  Division: dividend & divisor
• ${\displaystyle {\frac {x}{y}}}$  Division (fraction): numerator & denominator
• ${\displaystyle x^{y}}$  Exponentiation: base & exponent
• ${\displaystyle {\sqrt[{y}]{x}}}$  Root: index & radicand
• ${\displaystyle \log x}$  Logarithm: base & power
• ${\displaystyle x\backslash y}$  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
