Algebrus

Powerful and extensible computer system for scientific and technical calculations. No matter if you are a school student or recognized scientist, Algebrus serves your needs. It is easy to use and interactive means of solving problem in various areas of expertise. Console based scientific calculator, 2D and 3D graphs plotter, differential, algebraic and polynomial equation solver, unit converter, physical constants reference, statistical analysis, data fitting, programming environment, and many more. Or just simple “evaluate-while-typing” calculator for your everyday arithmetics. If it doesn’t have something needed, you can use built-in integrated syntax-highlighted XPascal programming environment to create your own routines and libraries, define your own types and operators.
