UltimaCalc Pro is an algebraic graphing calculator that is easy to use and can occupy only a little space on your screen, so you can keep it open and ready for use at all times, even on top of other windows.

The main window allows calculations to be expressed in mathematical form, in other words as expressions entered in plain text. You can edit what you typed and repeat the calculation.

UltimaCalc Pro has a large range of functions built in, including a function for evaluating definite integrals, and you can define your own functions too. What's more, it includes the Symbolic Algebra module.
