Word 2007 and Microsoft Math

Reading Alfred Thompson blog, who focus on computer science teaching at K-12 schools (what we call in Ecuador basic high school), I found this nice entry: Microsoft released a few days ago the Word 2007 Math Add-in. After installing and playing with it for just 2 minutes, I was able to create this document:

As you can see, the add-in lets you put formulas inside the text (including fractions, exponentials, sigmas, integrals, etc.), create graphs from an equation (I just typed in y = ...), and even solve those equations. Ah, this is the kind of stuff I would've loved to have at high school or college.

Speaking of which, the add-in seems to be based (I'm just especulating here) on Microsoft Math, an unexpensive stand alone product I wasn't aware of, that could be a nice present for a high school niece in love with physics or math.
