Divisibility Tricks with Modular Arithmetic

Hi everyone! In this video we look at proving a trick to know whether a number is divisible by 3 (no matter how large). The proof is surprisingly simple, and we use some modular arithmetic where numbers 'loop back' to zero at a certain point (just like the time of day).
