The free Mathomatic software, available on the official Mathomatic website, is authorized for use in any other type of software, due to its permissive free software license ( GNU LGPL).

The software does not include a GUI except with the Mathomatic trademark authorized, versions for smartphones and tablets running iOS or Android. "set debug 2" reveals even more details about the work done. Intermediate results (showing the work) may be displayed by previously typing "set debug 1" (see the session example) this works for solving and almost every command in Mathomatic. It also does summations, products, and automated display of calculations of any length by plugging sequential or test values into any formula, then approximating and simplifying before display.

Mathomatic excels at solving, differentiating, simplifying, calculating, and visualizing elementary algebra.
