There are an infinite number of different ways to add up numbers and get a sum of 17.
If you restrict the operation to only two positive whole numbers, then there are 16 ways
to do it ... each of the following, and its reverse:
1 + 16
2 + 15
3 + 14
4 + 13
5 + 12
6 + 11
7 + 10
8 + 9
10 plus 7
6+9
No two of those numbers add up to 17.
2 & 17
7, 13 and 17
false none of the numbers add up to 31
-25
The numbers are 15, 16 and 17.
54
No two of those numbers add up to 17.
2 & 17
8 + 9 = 17
7, 13 and 17
17 and 13
Add them up and you get 69 ;)
