What is the sum of a two digit number less the sum of its digits?

There exist no numbers which are less than the sum of their digits. This is obvious for single digit numbers, since each number would be exactly equal to the sum of its digits. For multi-digit numbers, this still holds true. Let's take a two digit number in the form: ab. Where a and b represen (MORE)

Two digit number is three more than 7 times the sum of it's digits?

If there are two digits than the first one is ten times its value. So as an algebraic equation we get 10A + B - 3 = 7(A x B) This can be simplified to 10A + B - 3 = 7A + 7B and this reduces to 10A - 7A = 7B - B +3 or 3A =6B +3 A solution to this is 3(3) = 6(2) +3 Which (MORE)
