We have $H=8-7=1$ and $T=8-2+5=11$. Clearly $1-11=-10$, so our answer is $A$. 
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\textquotesingle s answer is $H$~and Terry\textquotesingle s answer is $T$, what is $H-T$? (2014 AMC $8$ Problem, Question \#1)
