If 5 plus 2 equals 37 ---6 plus 5 equals 111 ---8 plus 2 equals 610 ---2 plus 1 equals 13 ---then 7 plus 9 equals?
Subtracted answer first, then added one after.5 + 2 = 37(5 + 2 = 7) and (5 - 2 = 3)3 and 76 + 5 = 111(6 + 5 = 11) and (6 - 5 = 1)11 and 18 + 2 = 610(8 + 2 = 10) and (8 - 2 = 6)6 and 102 + 1 = 13(2 + 1 = 3) and (2 - 1 = 1)1 and 37 + 9 = ?(7 + 9 = 16) and (7 - 9 = -2)-2 and 167 + 9 = -216i agree with your methods but wouldent it be 216 not -216?
