𝙎𝙞𝙜𝙣 𝙪𝙥 for Number Theory course (coming soon) on our website:
socratica.com/courses/number-theory
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.

About our Instructor:
Michael earned his BS in Math from Caltech, and did his graduate work in Math at UC Berkeley and University of Washington, specializing in Number Theory. A self-taught programmer, Michael taught both Math and Computer Programming at the college level. He applied this knowledge as a financial analyst (quant) and as a programmer at Google.
