Lesson 3 - Numbers

Numbers in Python

+ addition operator, e.g. 2 + 2 = 4
- subtraction operator, e.g. 10 - 6 = 4
* multiplication operator, e.g. 5 * 6 = 30
/ division operator, e.g. 8 / 4 = 2
% modulo operator, returns the remainder after dividing one number by another, e.g. 10 % 7 = 3
// floor division, first number or number at the left is divided by the second number or number at the right and returns the quotient, e.g. 47 // 10 = 4
