Mathematical Law One% is to take the remainder operation123% 9 = 6(1+2+3)% 9 = 63456795% 9 = 3(3+4+5+6+7+9+5)% 9 = 3(-123)% 9 = 3[-(1+2+3)]% 9 = 3The divisor will be credited as a1a2a3 ... An, the divisor is 9, the remainder is recorded as Q. Then there are:A1a2a3 ... An% 9 = Q1(a1+a2+a3+...+an)% 9 = Q2(-a1a2a3 ...
