What is Euler Math Toolbox (EMT) and how can it help you with mathematics?

Euler Math Toolbox (EMT) is

a powerful math program combining numerical and symbolic tools in one free and open source package,
a very advanced function plotter,
a matrix language, similar to Matlab,
a simple programming language,
allowing coding in Python and C,
providing a clean and simple interface that gives easy access to powerful tools,

available for all modern 64-bit Windows systems, and some Linux versions using the Wine emulator.

EMT is for you if

you are looking for a mighty, easy to use and free substitute for Matlab,
you need to do symbolic algebra or numerical mathematics in school or university,
you are a student or a teacher and want to demonstrate mathematics,
you want to make good looking mathematical illustrations or even photo realistic scenes,
you have a need to present mathematics on web pages.
