As for your puzzle at the beginning, you don't have to use Chinese Remainder Theorem. I think Chinese Remainder Theorem is a bit of a leap when you are just learning the mod notation. Try solving the puzzle yourself without the theorem and share where you are first.In this article we shall consider how to solve problems such as Find all integers that leave a remainder of 1 when divided by 2, 3, and 5. The Chinese Remainder Theorem: solved problems on chinese remainder theorem

By solving this by the Chinese remainder theorem, we also solve the original system. (The solution is x 20 (mod 56). ) Of course, the formula in the proof of the Chinese remainder theorem is not the only way to solve such problems; the technique presented at the beginning of this lecture is actually more general, and it requires no memorization.

The Chinese Remainder Theorem (CRT) is a tool for solving problems involving modular arithmetic. The theorem is called the Chinese remainder theorem because the Chinese mathematician Sun Tsu stated a special case of the theorem sometime between 280 and 473 A. D.

Chinese Remainder Theorem Example. Find a solution to x 88 (mod 6) x 100 (mod 15) Solution 1: From the rst equation we know we want x 88 6k for some integer k, so x is of the form x 88 6k. So from the second equation, we also want 88 6k 100 (mod 15), so we want 6k 12 (mod 15). Use the extended Euclidean Algorithm to nd that 15(1)6( 2) 3.

MATH 1365 SOLVED SAMPLE EXAM PROBLEMS 1. Find the coefcient of x7y2 in the expansion of (2y x)9. Solution. From the binomial theorem, we nd the coefcient to be ( 1)7 4 9 2 We use the Chinese Remainder Theorem, so we calculate rst the

Solve the simultaneous congruences x 6 (mod 11), x 13 (mod 16), x 9 (mod 21), x 19 (mod 25). Solution: Since 11, 16, 21, and 25 are pairwise relatively prime, the Chinese Remainder Theorem tells us that there is a unique solution modulo m, where m 11 16 21 25. We apply the technique of the Chinese Remainder

Sometimes, a problem will lend itself to using the Chinese remainder theorem in reverse. That is, when a problem requires you to compute a remainder with a composite modulus, it can be worthwhile to consider that modulus's prime power divisors. Then, the Chinese remainder theorem will guarantee a unique solution in the original modulus.

The Chinese remainder theorem is a theorem of number theory, The earliest known statement of the theorem is by the Chinese mathematician Sunzi in Sunzi Suanjing in the 3rd century AD. What amounts to an algorithm for solving this problem was described by Aryabhata (6th century).
