Mansour, Cool, that's what I thought. Did you take a look at SymJa ( https://bitbucket.org/axelclk/symja_android_library/wiki/Home )? They have an online demo set up ( http://symjaweb.appspot.com/ ) and I input your equation and got the following: Input: 2x - x^2 + 9 - 4 Output: -x^2+2*x+5 S

Michael, Indeed I am looking for a parser that can give me an array that math commons can accept. So iterating over the coefficients taking the order in account is necessary. For example: 3x + 7 - 8---> an array [3 -1] 2x - x^2 + 9 - 4 ---> [1 2 5] I was looking into Bills work, and trying

Bill, My interpretation of Mansour's original question was that he had an equation in the form "x + 3 = 10" and he needed to have a computer tell him x = 7. SymJa appears to solve more complex problems that that, at least from the limited documentation I saw, so it may be helpful? As for t

Someone else who is more experienced please jump-in here. My $0.02... 1. Would this be significantly different from SymJa? > https://bitbucket.org/axelclk/symja_android_library/wiki/Home I think we're talking about two different thing: 1) Mansour was asking for a library that can take a string
