In mathematics, an operand is one of the inputs (arguments) of an operator. Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and In Mathematics, an operator is a function which operates on (or modifies another function For instance, in
- 3 + 6 = 9
'+' is the operator and '3' and '6' are the operands.
The number of operands of an operator is called its arity. In Logic, Mathematics, and Computer science, the arity (synonyms include type, adicity, and rank) of a function Based on arity, operators are classified as nullary, unary, binary, ternary etc. In Mathematics, a unary operation is an operation with only one Operand, i In Mathematics, a binary operation is a calculation involving two Operands, in other words an operation whose Arity is two In Mathematics, a ternary operation is an N-ary operation with n = 3
In computer programming languages, the definitions of operator and operand are almost the same as in mathematics. A programming language is an Artificial language that can be used to write programs which control the behavior of a machine particularly a Computer. Programming languages generally support a set of operators that are similar to operators in mathematics.
Additionally, in assembly language, an operand is a value (an argument) on which the instruction, named by mnemonic, operates. See the terminology section below for information regarding inconsistent use of the terms assembly and assembler In Computer science, an instruction is a single operation of a processor defined by an Instruction set architecture. A mnemonic device (nəˈmɒnɪk is a Memory aid Commonly met mnemonics are often verbal something such as a very short poem or a special word used to help a person remember The operand may be a processor register, a memory address, a literal constant, or a label. In Computer architecture, a processor register is a small amount of storage available on the CPU whose contents can be accessed more quickly than storage In Computer science, a memory address is an identifier for a memory location at which a Computer program or a hardware device can store a piece of data A simple example (in the PC architecture) is
- MOV DS, AX
where the value in register operand 'AX' is to be moved into register 'DS'. See also X86 assembly language The generic term x86 refers to the most commercially successful Instruction set architecture in the history of Personal In the X86 assembly language, the MOV instruction is a Mnemonic for the copying of data from one location to another Depending on the instruction, there may be zero, one, two, or more operands. An instruction set is a list of all the instructions and all their variations that a processor can execute

-noun
- (mathematics) A quantity to which an operator is applied (in <math>3 - x</math>, the operands of the subtraction operator are 3 and <math>x</math>).
