Primitive Data Types, Arrays, Loops, and Conditions

Operators

Operators take one or two values (or variables), perform an operation, and return a value. Let's check out a simple example of using an operator, just to clarify the terminology.

>>> 1 + 2

In this code:

+ is the operator
The operation is addition
The input values are 1 and 2 (the input values are also called operands)
The result value is 3

Instead of using the values 1 and 2 directly in the operation, you can use variables. You can also use a variable to store the result of the operation, as the following example demonstrates:

>>> var a = 1; 
>>> var b = 2; 
>>> a + 1

>>> b + 2

>>> a + b

>>> var c = a + b; 
>>> c

The following table lists the basic arithmetic operators:

Operator symbol	Operation	Example
+	Addition	>>> 1 + 2 3
-	Substraction	>>> 99.99 – 11 88.99
*	Multiplication	>>> 2 * 3 6
/	Division...
