Answer:

2.

Explanation:

First, make sure you always solve from left to right when doing this. For this situation we need PEMDAS. This stands for: Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction. These are the steps that we need to follow to answer this question.

1.) First, we solve for the parenthesis. We can take the parenthesis down once we solve for that part. 2 + 1 = 3. Now we have: -3 ÷ 3 x 2 + 4.

2.) There are no exponents, so we move onto to multiplication from left to right. -3 ÷ 3 = -1. So, now we have -1 x 2 + 4.

3.) Now we do the right side of the problem with the multiplication. -1 x 2 = -2. Now we have -2 + 4.

4.) Because the larger number is positive, that means that the answer will be positive. So -2 + 4 (or 4 -2) = 2.

So, -3 ÷ (2 + 1) x 2 + 4 = 2.

I hope that this helps.

using PEMDAS
start with parentheses: (2+1)=3
-3 / 3 x 2 + 4
then you go in order from here
-3 divided by 3= -1
-1 x 2 + 4
-1 times 2= -2
-2 + 4 = 2
