Handle More Complex Math in Python

Python provides several additional math operations, including floor division (//) for integer division, modulus (%) to find the remainder after division, and exponentiation (**) for raising a number to a power.


              
12345678

            
# Floor division
print(18 // 4)

# Remainder of the division
print(18 % 4)

# Raising to the power
print(18 ** 4)
copy

These mathematical operations may seem confusing at first, especially with division and related operators, but they're actually quite simple.

Floor division gives the whole number result of division, while the remainder shows what's left. Exponentiation is multiplying a number by itself repeatedly.

Task

Swipe to start coding

You have $250 and want to buy as many cookie packs as possible, with each pack costing $6. Determine how many packs you can buy and how much money will remain.

  • Compute the floor division of 250 by 6 to find out how many full packs you can buy.
  • Determine the remainder when 250 is divided by 6 to see how much money will be left after buying the packs.
