# Free mobile alternative to step-by-step-solution feature of Wolfram Alpha Pro?

Are there any free online and/or offline alternatives to the step-by-step-solution feature of Wolfram Alpha Pro that can be used on Mobile phone?

This feature is able to display step-by-step-solutions of a wide variety of algebra problems.

Earlier there was SymboLab. Now their mobile version has gone paid.

SymPy Gamma is a free web application based on SymPy. It returns step-by-step solutions for some types of high school / college math problems, for example:

It's rougher around the edges and the syntax is a bit more rigid than WolframAlpha's. One can use ^ instead of ** for powers (there is some preprocessing for that) but otherwise, the closer you are to standard SymPy syntax, the better. For example, one can type integrate x*sin(3*x) instead of integrate(x*sin(3*x), x) and it's understood correctly. But when I tried integrate x**2/(x**2+1), SymPy Gamma misunderstood it as "the integral of x**2, divided by (x**2+1)".

It does not seem to have any step-by-step for algebra problems like "solve this quadratic equation", however.

(Disclosure: I am a SymPy developer, though I had no part in SymPy Gamma specifically.)

• $\sqrt{x^2-16} - (x-4) - \sqrt{x^2-5x+4}$ Commented Feb 25, 2018 at 9:04
• @AdityaPratapSingh you could use the fact that $\sqrt{x} = x^{0.5}$, so you could use x**0.5

## Integral Calculator & Derivative Calculator websites

Features:

• Both are free-to-use websites, which are also responsive on mobile phone screens.
• Both show steps
• The backend employs the CAS Maxima (GPL software).

Limitations:

• Unfortunately, you can only integrate and differentiate with respect to a single variable.
• The question has been modified because it was a duplicate. Now this question is about mobile. If your answer is not for mobile, please move it to softwarerecs.stackexchange.com/questions/16865/… thanks and sorry for the inconvenience! Commented Feb 26, 2018 at 4:28

Open Omnia is an alternative to Wolfram Alpha Pro and Symbolab. Disclaimer: I am the developer.
