Order of operations-Semester Exam Review Hey All!! Talking about order of operations today! As long as you follow PEMDAS and do your math correctly, you'll do great!!

Order of Operations-

Problem: -8+15/(-3)-2
Again, for this problem you are going to want to use PEMDAS. So your going to want to divide 15 by -3 which equals -5. Then your going to want to add -8 and -5 together and that is -13. This is what our problem looks like right now:
-13+-2=?
Now all we have to do is add -13 and -2 and we get -15!!
