Fix coprime moduli m1, . . . ,ms, of a few digits each. Let n be an integer of a few hundred digits. We show how arithmetic modulo n may be performed upon integers u represented as vectors (u mod m1, . . . , u mod ms). This method involves no multiprecision arithmetic, except in an easy precomputation; it is practical in software and extremely well suited for hardware. Our main tool is the Explicit Chinese Remainder Theorem, which says exactly how u differs from a particular linear combination of the remainders u mod mi.
