WebThe Chinese Remainder Theorem reduces a calculation modulo 35 to two calculations, one modulo 5 and the other modulo 7. The CRT, explained for this example, is based on a unique correspondence between the integers 0,1,\ldots,34 and the pairs ( u, v) with 0 \leq u < 5 and 0 \leq v < 7. The mapping from i,\ 0 \leq i < 35, to the pair ( u, v) is ...
