What grade are you in?

6. TheSmartOne

This stuff is basic things taught in elementary school...

7. TheSmartOne

We have to simplify parentheses first from left to right. Then we move on to exponenets from left to right. And then multiplication and division from left to right. And finally addition and subtraction from right to left. If it doesn't have one of them, then we skip that step and move on.

Im an incoming senior. But the education where I live is very low..and most teachers are lazy asf.

9. LeAnn01Xxx

And most teachers here are either on pills or are alcoholics

One way to remember PEMDAS|dw:1433953543671:dw|

You can start with finding the absolute value |-8| which is 8. Than add -3 to 8. After that divide 12/3. Than multiply what you got.

12. anonymous

Can you do that?

13. LeAnn01Xxx

Is it c?

14. anonymous

no

15. TheSmartOne

no

16. TheSmartOne

You have to follow PEMDAS, first do what brandon told you to do...

|dw:1433953927657:dw| Find the answers that are in the boxes

18. LeAnn01Xxx

Okay its either A or B obviously, and im thinking its A.

19. anonymous

12/3 * -3 + |-8| do absolute value first 12/3 * -3 + 8 now do division 4 * -3 + 8 now do multiplication -12 + 8 now do addition -4

20. anonymous

sorry I got that drawing wrong

21. TheSmartOne

@LeAnn01Xxx You aren't going to learn anything just by guessing.

22. TheSmartOne

So we now know it's not C. Well maybe it's D.

23. LeAnn01Xxx

Im not guessing. -.- excuse me for not being taught properly.

24. TheSmartOne

$$\color{blue}{\text{Originally Posted by}}$$ @LeAnn01Xxx Okay its either A or B obviously, and im thinking its A. $$\color{blue}{\text{End of Quote}}$$ In Math there is no such thing as thinking. It either is or it isn't.
