Question

Harry and Terry are each told to calculate 8−(2+5)8−(2+5). Harry gets the correct answer. Terry ignores the parentheses and calculates 8−2+58−2+5. If Harry's answer is HH and Terry's answer is TT, what is H−TH−T?

Answer 1

To evaluate the answer of Harry:
8-(2+5)8-(2+5)
= -55

To evaluate the answer of Terry:
8-2+58-2+5
= 66

HH = -55
TT = 66

H-TH-T
5-65-5
= -65
