As a high school student, I created this app after realizing the lack of an app that could fully help me while doing my calculus homework. Although the algebra was simple enough to do, it was a waste of time to do it for every problem. While there are apps and websites out there to help, none could function as a stand-alone calculator and always had to be supplemented with my graphing calculator or 3 other apps. Fed up with not having a powerful enough calculator, I made this as the ultimate homework helper (but it still has much use outside of school).
