P(A) is the power set of A. If you don't know what that means, don't guess on the question, because you won't answer properly.

Third Question:

Very tricky math! Note: This must be done in your head only.

Do NOT use paper and pencil or a calculator. Try it.



Take 1000 and add 40 to it. Now add another 1000. Now add 30..add another
1000. Now add 20. Now add another 1000. Now add 10.


What is the total? Did you get 5000?

I am trying to help my daughter with her homework. I know the rule of a negitive number and a negitive number makes a positive.
OK, I need someone to explain in very simple terms, why is a negitive # +/- another negitive # a positive number? Why is it I can't have a -12 +-10= -22 or even -2?
If at all possible, can someone explain this graphically as I learn better that way.
