    OK, so we know that m=3 and p=10. All we have to do is change the problem a little and then solve it! :)

    when m=3 and p=10 the problem would be this: 3x3x2+2x10x2-15.

    so all i would have to do is multiply those numbers then add & subtract, right?

    Right! PEMDAS. Do the multiplication first, then the adding, and last the subtracting.

    Ok, that is the wrong answer. Now I am going to break it down for the problem to be easier Do 3x3x2, then do 2x10x2. Let me know your answer with those two and then we can keep going.

    OHHHH! It's with exponents, and it took that away when you copied and pasted it! Ok here is what the problem really and truly should be like: 3x3^2+2x10^2-15. So first are exponents. Figure out what 3^2 is, and what 10^2 is.

    3^2 would be 9 & 10^2 would be 100 .. right?
