2(72-68)+2 / 5-5+10-5+10+10-15
ANSWER: 10/10
Actually, the answer would be either 1 or 13.4 depending on what proper mathematical rules you want to use, in that 8 (2(72-68)) + .4 (2/5) - 5 + 10 - 5 + 10 + 10 - 15 = 13.4 or 10 (2(72-68) + 2) / 10 (5 - 5 + 10 - 5 + 10 + 10 - 15) = 1. Either way, you cannot arrive at 10 as the answer to the mathematical equation you provided.
And I give your avatar a 7/10, it's good, but a little plain
