Functionality: 10/10

Usability: 9/10

This program was very handy for me; however, it is best suited to those still exploring geometry and algebra rather than calculus. I found that it did a lot of tasks which many other programs exclude.

However, the UI was slightly clumsy. To use its more advanced features, the user has to enter twice to access special functions involving the main menu. In addition, I initialy found the altering-menu slightly annoying (it can be turned off). Also, I found that everything was stuck in a menu, which takes some slight memorization.

Overall, it was a great, useful program that just needs some minor UI tweaks.
