A) 2
B) -13
C) -18
D) -17
E) non of the above

The OA is the option B.

Why is B? I've got D=-17. Can anyone give me some help here? Thanks.

Hello M7MBA.

Let's see. The given expression is the same as $$3-\left(3\cdot6\right)+2\ .$$ Just that it last one has parenthesis. If we solve it, we will obtain: $$3-\left(3\cdot6\right)+2\ =3-\left(18\right)+2=5-18=-13.$$ Therefore, the correct answer is the option B.

I think you got the wrong answer because you solved the following equation: $$3-\left(3\cdot6+2\right)\ =3-\left(18+2\right)=3-20=-17.$$
