Mathematical operators in Python work in similar ways to how they work in math.

Operator	Description	Example
+	Addition	a + b = 30
-	Subtraction	a – b = -1
*	Multiplication	a * b = 100
/	Division	b / a = 2.0 *division by zero throws an error
%	Modulus	b % a = 1

Working with decimals

One thing to note is that when decimal numbers and integers are mixed in a statement, decimal numbers are given as a result.

Example - 1:

a = 1.0

b = 2

print(a - b)

OUTPUT: - 1.0

Example - 2:

a = 1.0

b = 3

print(a * b)

OUTPUT: 3.0

Order of operations

Python follows the order of operations just like math which goes:

parentheses >> multiplication/ division >> addition/ subtraction

Example - 1:

print( 5 + 1 * 2)

OUTPUT: 7

Example - 2:

print( 3 / 2 - 1 * (3 - 1))

OUTPUT: - 0.5

Modulus %

Modulus is super useful in programming. Modulus divides the left-hand operand by the right-hand operand and returns the remainder.
