The numbers in an arithmetic operation are called operands.
The operation to be performed between the two operands is defined by an operator.

Assignment

The assignment operator (=) assigns a value to a variable.

var x = 10;

Addition

The addition operator (+) adds numbers:

var x = 5;
var y = 6;
var z = x + y;
                                    

Multiplication

The addition operator (*) multiplies numbers:

var x = 5;
var y = 6;
var z = x * y;
                                    

Arithmetic operators are used to perform arithmetic operations on numbers.

Next, we will explore conditionals, which make use of comparison operators.
