WebFeb 10, 2024 · Example: using the Chinese remainder theorem Say that your mom bought a few handfuls of sweets and would like to give them away to you and your three siblings. However, she knows all too well how her children hate when we give one more than the others, so she quickly counts the candies. Oh, bother! WebJul 18, 2024 · An example of this kind of systems is the following: find a number that leaves a remainder of 1 when divided by 2, a remainder of 2 when divided by three, and a remainder of 3 when divided by 5. We shall see that there is a systematic way of solving this kind of system. Theorem 2.3.1: The Chinese Remainder Theorem Fix a k ∈ N.

WebFor example, the remainder when x^2 - 4x + 2 is divided by x-3 is (3)^2 - 4 (3) + 2 or -1. It may sound weird that plugging in A into the polynomial give the same value as when you divide the polynomial by x-A, but I assure you that it works.
