Overview
Unfortunately, this homework doesn't have any graphs, formulas, maps, or diagrams. :-(
That means you can do the whole thing on your computer or tablet. Just download the homework, then open Adobe Acrobat Reader, and fill in the answer fields!

Remember that there's a bug which sometimes causes the answers to not save. If that happens to you, I recommend that you Google "flatten PDF" and follow the instructions applicable to your hardware and software.
