SUMMARY

The discussion focuses on the mathematical relationship between congruences, specifically how to relate the variable b with moduli m and n. It establishes that if a is congruent to 0 modulo m (a ≡ 0 (mod m)) and a is congruent to b modulo n (a ≡ b (mod n)), then a can be expressed as a = k1m and a = k2n + b. This leads to the conclusion that b can be derived from the values of m and n through the manipulation of these equations.

Suppose we have ##a \equiv 0 (mod~ m)##. And, ## a \equiv b (mod~ n)##. Is there any way to relate ##b## with ##m## and ##n## ?

Your first equation is equivalent to a = k1m, and the second is equivalent to a = k2n + b.
