KAlgebra is a mathematical calculator based on content markup MathML language, capable to make simple MathML operations (arithmetic and logical) and to representate 2D and 3D graphs.
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.
Application may crash on saving plots due to KAlgebra native bug.
