2.2 Basic Operators

Just like in mathematics, Python allows you to perform various mathematical operations such as addition, subtraction, multiplication, division, and more.

Here are the basic operators in Python:

Operator	Description	Example
+	Addition	5 + 2 = 7
-	Subtraction	5 - 2 = 3
*	Multiplication	5 * 2 = 10
/	Division	5 / 3 = 1.67
%	Modulo (Remainder)	5 % 3 = 2
**	Exponentiation (Power)	5 ** 3 = 125
//	Floor Division (Integer Div)	5 // 2 = 2

These operators are fundamental in Python and are used extensively for mathematical computations.

Example Usage:

Let's see how we can use these mathematical operators in Python:

print(5 + 7)  # Addition: Outputs 12
print(5 - 2)  # Subtraction: Outputs 3
print(5 * 2)  # Multiplication: Outputs 10
print(5 / 3)  # Division: Outputs approximately 1.67
print(5 % 3)  # Modulo (Remainder): Outputs 2
print(5 ** 3) # Exponentiation (Power): Outputs 125
print(5 // 2) # Floor Division (Integer Div): Outputs 2

These examples demonstrate how each operator works in Python and what results you can expect. Understanding these operations is crucial for performing calculations and manipulating data in Python.
