Have you ever heard of Microsoft Math? It’s a downloadable product for students which features a graphing calculator, formula & equations library, triangle solver, unit conversion tool, and more. Math is pretty affordable at only $14.95 (U.S.), but that’s not the free Math download I’m referring to in this blog post’s title. The free download I’m talking about is a Microsoft Math add-in for Word 2007 users. This add-in lets Word handle things that you may have thought only Excel was capable of doing. With the Math add-in, for example, you can create graphs, perform calculations, and solve for variables – and all from within Word. You can even plot elements in 2-D and 3-D. This is great for those who are writing research papers on mathematical subjects, for teachers who are creating study guides for students, as well as anyone else who needs to do some math in Word. But you won’t find this free add-in on the Microsoft Math homepage, though – you’ll need to go straight to this page on the Microsoft Download Center site instead.
