This movie is about a woman, whose job is a housekeeper, who takes care of this professor. Apparently, he has only 80 minutes of memory and can only remember clearly what has happened till 1975 (this movie's year was 1985). So every day, they have the same greetings and such.

One day, the professor requested for the woman to bring her son over everyday after school so he won't be left alone. And since then, the professor has taught them many things about maths.

For example,

24 is a factorial of 4, which also means,

1x2x3x4 = 24! (:

220 and 284 are a pair, which also means,

220's divisors add up to 284, and 284's divisors add up to 220! :D Cool huh!

And the professor's beloved equation is.....

e^(pi * i) + 1 = 0 !!

e = 2.71828182845904523536........

pi = 3.14159265358979323846.......

i = imaginary number

It's such a wonder for this equation, which is also called Euler's Identity! (: Awezome huh!
