In many cases, modulo operations are used. Here we describe some pattern operations and prove them. The practical application of these theories will be recorded and explained in the future. 1. The modulo operation is a remainder operation (recorded as % or mod), which has the characteristics of periodicity. M % N indicates the remainder of N after division of M. When M increases, M % N is cyclical, and the
