The app contains a bunch of different calculators that help with homework, or are just cool in general.
It has a main screen where you choose what calculator you want to use.
Having the set calculators include a multiplication sign, so that data pieces can repeated a certain number of times with typing it all in. E.g. 5, 2*4, 8*3 and the data set would contain one 5, four 2s, and three 8s; as opposed to 5, 2, 2, 2, 2, 8, 8, 8
Fixing exponential and sinusoidal calculators.
Adding physics, chemistry, more polynomial, derivative, etc. calculators.
Organizing calculators on the main page according to type.

All of these are adjustable at any time, so if any of them aren't formatted
perfectly for your phone, or could be better in any way, email me (michael@mikeyaworski.com)
or contact me somehow with an update suggestion. Tweet to @mikeyaworski
I will constantly be updating this app and adding more things to it
as I get more ideas.
Any updates I make to this app will be noted on this webpage.
