- In the arithmetic expression , the numbers and are the operands for the addition operator ().
- In the logical operation , the variables and are the operands for the AND operator.
- In a computer programming instruction like , and are operands for the move operation.
Advanced Usage

- Example: In the expression
-7, the number7is the sole operand for the unary minus operator.
- Binary Operand: An operation that uses two operands (the most common type).
- Example: In
x / y,xandyare the binary operands for the division operator.
