who knows the answer to 2*2604(52/9)/7*43+62/56

I do. Have you considered pasting that problem into the Google Search window, and pressing enter?

I am wondering why this is called advanced math.

Not off the top of my head, I don't.

I'm in 7th grade advanced math and we get to use calculators.

Can you use a calculator?
If so, you can enter this.

I have a scientific calculator, it's really nice to have aroud for probblems like that!
