Algebra and Vector Algebra-simpleNeasyApp by WAGmob

This is a great app for anyone looking to refresh on some math. Everything is very clear and accurate. This is one of my favorite apps!

Limited access is right - the first 2 chapters.

I need help accessing the program as a member

It won't let me sign up and stuff. Won't let me pass the first one. Keeps saying Authorization header not valid. I really liked the app and probably would have bought them all but now i don't know.
