Some Free February Appy-ness with a new piece of free software for teachers from Microsoft every day in February. Many of these items are unknown heroes, but they all share two things in common: 1) They are useful for teachers or students and 2) they are free.

## Mathematics Add-in for Word

Microsoft Mathematics Add-in for Word and OneNote makes it easy to plot graphs in 2D and 3D, calculate numerical results, solve equations or inequalities, and simplify algebraic expressions in your Word documents and OneNote notebooks.

It works with Microsoft Word 2010, Microsoft Office Word 2007, and Microsoft OneNote 2010. With this add-in, you insert an advanced math problem (from algebra to calculus, physics, or statistics) and then click to simplify complex expressions or to solve. Use these advanced math computational and graphing capabilities to: Plot a function, equation, or inequality in 2-D or 3-D, and save the results, solve an equation or inequality, calculate a numerical result, compute the inverse of a matrix, matrix operations, list operations, and integrals.

#### Mathematics Add-in in detail

With the Microsoft Mathematics Add-in for Word and OneNote, you can perform mathematical calculations and plot graphs in your Word documents and OneNote notebooks. The add-in also provides an extensive collection of mathematical symbols and structures to display clearly formatted mathematical expressions. You can also quickly insert commonly used expressions and math structures by using the Equation gallery.

• Compute standard mathematical functions, such as roots and logarithms
• Compute trigonometric functions, such as sine and cosine
• Find derivatives and integrals, limits, and sums and products of series
• Perform matrix operations, such as inverses, addition, and multiplication
• Perform operations on complex numbers
• Plot 2-D graphs in Cartesian and polar coordinates
• Plot 3-D graphs in Cartesian, cylindrical, and spherical coordinates
• Solve equations and inequalities
• Calculate statistical functions, such as mode and variance, on lists of numbers
• Factor polynomials or integers
• Simplify or expand algebraic expressions

### Where can I find out how to use it?

In addition to the step-by-step tutorial document for to the Mathematics Add-In, there is also a handy Teachers Guide to the Mathematics Add-In.

And finally, there’s a video demo tutorial below, which walks you through the software and how to use it.
