An application with several exercise types in order to enhance your calculating with fractions. Different tasks include exercises to find the sum of two fractions, the conversion of fractions into the respective decimal, the comparison (with less than, more than) of fractions, and more.

A great application with interactive geometry. Ideal for teachers attempting to draw a graph on the computer, or students who wish to find out more and investigate with graphs and curves. Currently many things are supported, and you can very easily construct several things from parabolas and hyperbolas, to ellipses.

Essentially an application to help you improve your skills in calculating percentages. Different exercises are included, and there are varying difficulty levels to target persons with varying abilities.

A mathematical function plotter. It has built in a powerful parser. You can plot different functions simultaneously and combine their function terms to build new functions. KmPlot supports functions with parameters and functions in polar coordinates. Several grid modes are possible and plots may be printed with high precision in correct scale.
