In ancient times, integers were simply called "numbers", hence "number theory". Scholars pulled apart numbers - slicing and dicing them - looking for interesting properties which might explain things like why a month is ~28 days long. One approach involved looking at the divisors of an integer. Integers with a LOT of divisors were called "abundant". Those were very few were called "deficient". And some integers seemed to have a near-magical number of divisors and were called "perfect".

In this lesson we'll explore abundant, deficient, and perfect numbers.
