Simplify. –24 – 8 ÷ (–4) <br> A. –22 <br> B. –8 <br> C. –26 <br> D. 8
pishuonlain [190]
Hi there! The answer is A. - 22 

We can use PEMDAS to find our answer, which says divide first (before adding).

- 24 - 8 : (-4) = 

Since we divide two negative numbers, we end up with a positive value.
- 24 + 2 = 

Now we can add 
-24 + 2 = -22
