Comments
- I've used a number of maths algebra tools all the way from MuMath (does anyone remember that?) , to Derive, Matlab and Maxima. This allows to do everything that I need to and not have to put in superfluous notations such as 3*x when 3x can do. Also like the fact that there is a button for functions such as solve and expand. The real thumbs is that on a phone even this is betetr than the msdos derive which i liked using.
- Any chance that this app will be able to read a script in the near future? That would make it a very effective tool. Keep up with the development great achievement so far.
- Android REDUCE is wonderful. I'm an MBA student at the University of Jijiga, and there's so much that I need in here. I can't wait the updates. Thnx.
- That's a decent algebra app, it can be developed further into something great if you put enough work into it
- Vereinfacht leider nicht immer maximal (Beseitigung von Klammern)... Aber verkürzt den Term immer!
- Not so comprehensive command line to the new ones. But Powerful in which it promises!
- Excellent job, the app is very powerful and simple to use.
- This is useful for my homework
