Create some simulated variables

x = 6
y = 9

x plus y

print(x + y)

15

x minus y

print(x - y)

-3

x times y

print(x * y)

54

the remainder of x divided by y

print(x % y)

6

x divided by y

print(x / y)

0.6666666666666666

x divided by y (floor) (i.e. the quotient)

print(x // y)

0

x raised to the y power

print(x ** y)

10077696

x plus y, then divide by x

print((x + y) / x)

2.5

Classics vs. floor division. This varies between 2.x and 3.x.

Classic divison of 3 by 5

print(3 / 5)

0.6

Floor divison of 3 by 5. This means it truncates any remainder down the its

"floor"

print(3 // 5)
