Mathematics unites up to 300 highly interactive subjects and lessons, that can work as a complement to any textbook.
You can insert your own values in the calculations and check the results, draw graphs (that can be recalculated, rescaled or done in colour), make presentations, access explanatory texts, easily browse among different subjects, etc. It is a program to improve, learn, study or revise.
Also, the Mathematics content can be copied and pasted to be used elsewhere, i.e. work on them in your notes, the classroom, etc.
