In programming, operands are the values or expressions that are operated on by an operator. In Kotlin, operands can be variables, literals, or expressions that evaluate to a value.

For example, in the expression `num1 + num2`

, `num1`

and `num2`

are the operands and `+`

is the operator. Similarly, in the expression `a * b - c`

, `a`

, `b`

, and `c`

are the operands and `*`

and `-`

are the operators.

Kotlin has many different types of operators, including arithmetic, assignment, comparison, and logical operators, each of which operates on one or more operands. By using operators and operands, you can write expressions that perform calculations, compare values, assign values to variables, and much more.
