Parenthesis are your friend when in doubt use them :) 10x^2+9x/5x^2+3x is not the same as (10x^2+9x)/(5x^2+3x) People should use http://www.wolframalpha.com/ to show you in how humans view it and see difference. We call it pretty print. Anyone else know similar sites like wolfram? I heard of http://www.numberempire.com/ is good too.

A history of Mathematica. http://www.wolfram.com/company/mathematica-history.html I currently own a purchased copy of Mathematica 8.04 Home Edition that is used to solve and verify the solutions presented on this site.

OpenStudy (anonymous):

but paying for it is too much

If you are an academic or an active student in school, Wolfram offers Mathematica at very reduced prices. By the way, the version 8 installation media is on the order of 1 giga bytes and contains over 3000 functions.

1 gig for math? Wow I have a ti 89 that does a lot of calc stuff and symbolic algebra. i doubt it has 1 gig of memory.

Running my copy on a mid 2010 Apple IMac with 8Gb of ram. Able to run a native version of Mathematica, two virtual versions of Windows, XP Pro and 98SE, and two virtual versions of Linux, Ubuntu and Debian, simultaneously. Each virtual OS appears as a window on the desktop. Can copy and paste between each OS except 98SE. A full screen capture of my machine is attached.

OpenStudy (anonymous):
