KAlgebra is a fully featured calculator that lets you plot different types of 2D and 3D functions and to calculate easy (and not so easy) calculations, such as addition, trigonometric functions or derivatives.
The application has been thought to be progressively understood for students, so that starting to use it doesn't get in the way.
The language is deeply integrated with the UI, providing a dictionary with representations for all the available operations, code highlighting and code completion.
Installation into Linux Mint:
sudo apt-get isnstall kalgebra
