Excellent

Im a student who takes a couple of more advanced math classes, as well as computer science, and the default calculator in iOS did not fit my needs. This is far better, and was definitely worth the money. The interface is a little confusing at first, but once I figured it out, I found that this was just about perfect for me. I love being able to link equations so easily.
