Microsoft Mathematics is an add-on to Word and OneNote that allows you to enter equations, solve some of them, and draw two-dimensional and three-dimensional graphs. Microsoft Mathematics has a very intuitive visual equation editor that allows you to enter elegantly complex mathematical formulas into documents and notes, also typing them manually on the touch screen. In addition, many of them are able to solve, for example by finding the value of a variable in an equation, integrating or differentiating.

The add-on can operate on real and complex numbers, and calculate trigonometric functions in radians, degrees or grades. In addition, the add-on allows you to draw charts in two and three dimensions, for which it uses DirectX. The chart can of course be inserted into the edited document.

To work properly, the program requires .NET Framework 3.5.
