Mathematical Operations in Python

In this lesson, I will explain how to perform the main mathematical operations in the Python language.

Addition

The addition operator is the symbol "+"

>>> 1+2
3

Subtraction

The subtraction operator is the symbol "-"

>>> 4-1
3

Multiplication

The multiplication operator is the symbol "*"

>>> 3*4
12

Division

The division operator is the symbol "/"

>>> 10/4
2.5

The result of the division is always a float.

Floor Division

The floor division operator is the symbol "//".

Floor division rounds the quotient of the division down to the nearest integer.

>>> 10//4
2

In this case, the result is always an integer type.

>>> type(10//4)
<class 'int'>

Modulo

The modulo operation gives the remainder of a floor (integer) division. It's represented by the % symbol.

For instance, when dividing 10 by 3, the remainder is 1, as 3 times 3 equals 9.

>>> 10%3
1

It's worth noting that the result is always an integer type (int).

Exponentiation

The exponentiation operator is the symbol "**"

>>> 2**4
16

I hope this lesson helps you understand how to perform basic mathematical operations in Python.
