Yeah it's a bit of a bummer that most calculators don't have a modulo button.

I was sitting there in my cryptography exam the other day trying to do stuff like 361 (mod 36) by manually doing ANS-36 until a value <35 showed up. Pretty annoying when you have to perform it repeatedly.

Alternately to do (a mod b), you can try (for most cases):

x = floor(a / b);
remainder = a - (x*b)

That's just 2 steps to do even ridiculous modulos.

Most TIs should have a mod function, but unfortunately, most of those calculators aren't allowed in exams :S
