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.
wolfram do good software. i have heard lots of good things about "mathmatica"
mathmatica is wolframs software or a different one?
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.
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.
your desktop is a mess :P
