Some Thoughts re: sum not product Comment 4 of 4 |
(In reply to sum not product by xdog)

Apparently I've solved a wrong QUESTION and even there missed the case of 2,3,C , C being an odd number  bigger than 3.

So  the answer is (A,B,C)=(2,odd1,odd2) with the possibility of one of the odds being 3 and ignoring the symmetrical solutions.


  SUM (A+B+C) can be any of 0,2,4

PRODUCT  (A*B*C) - 2,3, or 4
