anonymous 4 years ago -4 20 20 I can't tell if I add the 20's, or subtract them.

1. anonymous

That's the exact format of the problem?

2. anonymous

Here it is again. I didn't realize my user name would get in the way. -4 20 20

3. anonymous

Well, I mean, without anything else, that's just a list of numbers.

4. anonymous

I suppose the answer *could* be 36....

I really don't understand the question either. It literally just looks like a list of numbers. Is there any words along with the problem, any context?

8. anonymous

No, just the numbers. Maybe the answer is 36.

Ok. Thank you.

Simplify the absolute value expression: -[8]

12. anonymous

Notice the notation there.$\Large \begin{array}{l} \left| { - 8} \right| = 8\\ - \left| 8 \right| = - 8 \end{array}$

13. anonymous

Thank you.

-10+(-9)-(-20)

15. anonymous

It's probably best to post these as new questions. But... $\Large \begin{array}{l} - 10 + ( - 9) - ( - 20)\\ = - 10 - 9 + 20\\ = - 19 + 20\\ = 1 \end{array}$

Yes, I just realized I was posting in the wrong box. Thank you.
