Nice work! Python provides several additional math operations, including:
//- floor division or integer division;%- modulus or remainder after division;**- exponentiation or raising to a power.
It's important to note that you can't use the traditional ^ symbol for exponentiation in Python, as it yields a different result. The syntax for these operations mirrors that of basic arithmetic. For example, 18 // 4 results in 4, because we're taking the whole number from the division (the actual result being 4.5). 14 % 5 gives 4, because when we divide 14 by 5, the remainder is 4. 4 ** 3 results in 64, because 4 multiplied by itself three times equals 64.
# Default division print(18 / 4) # Floor division print(18 // 4) # Remainder of the division print(18 % 4) # Raising to the power of 4 print(18 ** 4)

- On the second line, compute the floor division of
234by32. - On the fifth line, determine the remainder when
356is divided by17.
Why are these operations helpful?
For instance, picture this scenario: You've got $50 and you want to buy as many cookie packs as possible, with each pack priced at $6. You're trying to figure out the max number of packs you can purchase and the change you'll receive. Using the operations above, you can solve this easily.
50 // 6gives8, which means you can buy 8 packs;50 % 6results in2, indicating you'll have $2 left after buying 8 packs.
