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?

Given:


Harry and Terry are to calculate
8−(2+5)8−(2+5)


Harry go the right answer


Terry got 8−2+58−2+5



Find: H-TH-H



Solution


First, you have to get Harry’s
answer, H


H = 8−(2+5)8−(2+5)


H = 8−(7)8−(7)


H = 8−56−7


H = -48-7


H = -55



Then get Harry’s answer, T

 T = 8−2+58−2+5

 T = 6+58-2+5

 T = 64-2+5

 T = 62+5

 T = 67


 
Find: H-TH-H

 -55-(67)(-55)-(-55)

 -55-(-3685)-(-55)

 3630+55

3685
