What does operand mean?
An operand is a value or quantity that takes part in a mathematical, logical, or computational operation, with the term usually identifying the value on which the operation is performed. In the expression 8 + 3, for example, 8 and 3 are operands, while + is the operator. In computer architecture and programming, an operand may be a register, memory location, constant, or other data item supplied to an instruction. The word is therefore strongly associated with precise technical description rather than everyday speech. Its distinction from operator is useful: operands are the elements being acted upon, whereas an operator is the symbol or instruction governing the action. Understanding the term helps make descriptions of arithmetic, logic, and computer processing clearer and more exact.
nounA quantity or element on which an operation or mathematical procedure is performed. In computing, it is commonly a value supplied to an instruction or operation.
- A quantity or element involved in a mathematical or logical operation, especially one on which the operation is performed.
- A value or data item supplied to a computer instruction or program for processing.
"The calculator adds the second operand to the result stored in the accumulator."
"In the expression 7 × 6, 7 and 6 are the operands."
"The processor retrieves the operand from memory before performing the operation."
The standard plural is used when referring to multiple values involved in one or more operations.
"The instruction adds the two operands and writes the result to memory."
In a command-line calculation, the numbers you type are operands, while the + or − sign is the operator.

Etymology of operand
The word comes from the Latin gerundive operandum, meaning “that which is to be operated” or “the thing to be worked on.” It was adopted into English in the 19th century in mathematical and computational contexts. Its root is the same Latin word associated with operate, operation, and operator, all of which concern performing or applying an action.

How operand is actually used
Technically precise and especially common in mathematics, computing, and digital logic. The term is less common in general conversation, where input or number may be used instead.
Easily confused with operand
An operand is the value on which an operation acts, whereas an operator is the symbol or instruction that specifies the operation, such as + or ×.
