A comprehensive scientific calculator app

Yes, your droid comes with a calculator and you might even already have an additional calculator app. However, if you are surviving high school or are in any scientific degree in college, those toy calculators aren't enough. You need to solve quadratic equations and polynomials and vectors and matrixes and draw graphs and all that odd Math stuff we mere mortals can't understand. Perhaps you need to save it all and bring it with you to your PC.

Graphing Calculator is an insanely complete app, thought for helping any need any algebra student may need. It also comes with a smooth interface and a supporting website and email address.

This pro version comes free of ads and can be run offline.

Developer's original description available here
Graphing calculator with algebra. Essential tool for school and college. Replaces bulky and expensive handheld graphing calculators.

Multiple functions on a graph, polar graphs, graphing of implicit functions, values and slopes, roots, extremes, intersections. Algebra: polynomials, polynomial equation solving, matrices, fractions, derivatives, complex numbers and more. Shows results as you type. Use menu to switch between modes.

    This app is very nice for quick calculations and quick graphical results. And it is quite cheap for what it does. Would love to have more CAS (Computer Assisted Algebra) capability and 3D graphing

    I haven't found anything yet I haven't been able to do. It will show you step by step of your problem. Once you get the hang of it you will love it! Aced all my algebra assignments and tests with this app! Worth every penny for the pro version.

    I am going back to College after 14 years and my 200$ engineering calculator is fried, so I look on app store and found this Gem! It is awesome for only 5 bucks! Kids today you guys are so lucky! Calculator does more than my handheld

    I'm wondering why in a such complex and powerful app there's no build in integration, boolean algebra .. etc ,, etc. Other than that, It's a great app that proves useful, except for the obvious lack of integrals that would make it more complete and far more superior.
