Problema Solution
Harry and Terry are each told to calculate 8−(2+5) . Harry gets the correct answer. Terry ignores the parentheses and calculates 8−2+5 . If Harry's answer is H and Terry's answer is T , what is H−T ?
Answer provided by our tutors
Harry gets the correct answer: 8 - (2 + 5) = 8 - 7 = 1 that is H = 1
Terry's answer is: 8 - 2 + 5 = 6 + 5 = 11 that is T = 11
H - T = 1 - 11 = -10
