E) non of the above
Given: 3 - 3 x 6 + 2
Must must perform all divisions and multiplications first.
So, 3 - 3 x 6 + 2 = 3 - 18+ 2
Next, when given the options of subtraction and addition, we perform the operations from left to right
So, we get: 3 - 18 + 2 = -15 + 2
= -13
Answer: B

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: $$3-\left(3\cdot6+2\right)\ =3-\left(18+2\right)=3-20=-17.$$
