**Operands**

*Operators* operate on *operands*.

Stated differently, *operands* are the things that are operated on by *
operators*.

For example, in the following expression, the **plus
character** is an operator while **x** and **y** are operands.

`x + y`

Assuming that **x** and **y** are numeric
variables, this expression produces the sum of the values stored in the two
variables.

The variable **x** would be called the *left
operand* and the variable **y** would be called the *right operand.*
