### Chinese Remainder Theorem

The book on Discrete Mathematics by Rosen is really good. A joy to share time with. Very clear explanations. Of the Chinese Remainder Theorem for example. I have a so called "excellent" book on Number Theory from Dover publications in which the CRT seems too difficult to understand by a mortal. Rosen cuts through it right away. Mathematics is always simple once you understand it. Why not keep it simple when communicating it to students? - Anyway. The CRT is an algorithm for solving systems of linear congruence equations. Like for example.
$$\begin{cases} x \equiv 1 \bmod{3} \\ x \equiv 2 \bmod{5} \\ x \equiv 3 \bmod{7} \end{cases}$$
which has solution $x=52 \bmod{105}$ which can simply be verified like $52 \bmod{7} =3$ because $52 = 7.7 + 3$.

## Welcome to The Bridge

Mathematics: is it the fabric of MEST?
This is my voyage
My continuous mission
To uncover hidden structures
To create new theorems and proofs
To boldly go where no man has gone before

(Raumpatrouille – Die phantastischen Abenteuer des Raumschiffes Orion, colloquially aka Raumpatrouille Orion was the first German science fiction television series. Its seven episodes were broadcast by ARD beginning September 17, 1966. The series has since acquired cult status in Germany. Broadcast six years before Star Trek first aired in West Germany (in 1972), it became a huge success.)
