WebThe rule for 7 works similarly. 10H+T is a multiple of 7 if 20H+2T is. Subtracting 21H (a multiple of 7), we get 2T-H. So if 2T-H (or its negative, H-2T) is a multiple of 7, so is 10H+T. Several of the other divisibility rules work the same way. The rule for 19 works because 19 is one less than 2*10. The rule for 17 works because 3*17 is one ...
