Does anyone know of any good math apps for the WebOS? I'm trying to get my math skills back up to help me pass the nursing Compass test. I have a few math apps, but would like to find more. I haven't had to use most of my math skills in years and years, so I have forgotten a lot of them. I just want to find apps that will give me a good starting point. The Compass test deals with Pre-Algebra math, like Fractions, Geometry, Ratios, Multiplying, Dividing, ect.

Any suggestions?

I already have:
1. Brain Challenge
2. Math Magic
3. Multiplication Master
4. Alphacards
