Visual description of how the Chinese Remainder Theorem allows you to split a linear congruence into two simpler linear congruences. This is useful in cryptography when you want to work modulo n=pq where p and q are large, distinct primes. [Smurf mode is possibly easier on the eye than a whiteboard? Any comments/suggestions welcome]

This work is based on modular arithmetic and Euclid's algorithm like an hour hand comes back to zero hour every 12 hours. 16 speakers reproduce sound at different speed and pitch each other. So even if 16 sounds start as one sound and one rhythm , they are soon to be scattered and led into poly meter as time goes by. Eventually they come back as one sound. It has simply16 clocks moving at different speed .

In this video we introduce the fundamental concepts of floor and ceiling. We discuss an anomaly that occurs in modular arithmetic with negative dividends and/or negative divisors. The division algorithm and the resolution to this issue are amplified upon with the help of examples. Concerns in programming languages are addressed.
