1e math

This essay is the first of my blog math class, I think it is better to write some feelings. The mathematical class in this algorithm is generally to solve some of the tolerance, number theory, or combinatorial mathematics and other problems. But

Topic linksGive two number n, M. to find the value of n%1+n%2+.......+n%m.First, n%i = N-n/i*i, then the original conversion is N*m-sigma (I:1 to M) (N/i*i).Then we can find 1/4 = 2/4 = 3/4 = 0, 4/4 = 5/4 = 6/4 = 7/4 = 1. So you can divide these
