Subtracted answer first, then added one after.
5 + 2 = 37
(5 + 2 = 7) and (5 - 2 = 3)
3 and 7
6 + 5 = 111
(6 + 5 = 11) and (6 - 5 = 1)
11 and 1
8 + 2 = 610
(8 + 2 = 10) and (8 - 2 = 6)
6 and 10
2 + 1 = 13
(2 + 1 = 3) and (2 - 1 = 1)
1 and 3
7 + 9 = ?
(7 + 9 = 16) and (7 - 9 = -2)
-2 and 16
7 + 9 = -216
i agree with your methods but wouldent it be 216 not -216?
