A calculator that solves many types of problems including
solving equations
computing derivatives and integrals
simplifying expressions
graphing equations 2d and 3d
reverse polish notation, algebraic and word based interpreter
infinite writing board for writing out equations
requires java 11 or more
Goal of this project is, creating a calculator that can handle all date and time operations that a user may need.
You can operate with milliseconds as months, years or dates.
Examples:
2013-11-25 + 3d => 2013-11-28
2013-11-25 - 2013-10-20 => 36d 1h
5h + 6h => 11h
1382220000t => 2013-10-20
