The answer is D because you have to sneer what is in the parentheses first 
denonakavro
Always parenthesis first. So now we have (120-(5+10x7))
In the parenthesis, again the parenthesis goes first
SO we have (5+10 x 7)
Now multiplication goes first
10 times 7
So the very first thing you should do in this question is to multiply 10 by 7
