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.

    wery usefull, intuitive, good looking, many good features, I bought it instantly after tried it out. worth every peny. Though I would like to have some featues if possible, since i am an electronist an programmer I need to do fixed point calculations, it would be nice to have a function to extract the integer part from a result, and to be able to convert hexa <-> decimal (like it is done fo

    The only problems with this is that I can't use it at school (school rules) and the surprisingly low downloads of such a useful app

    A very good calculator with most of the functions of a graphing calculator but it would be helpful if you could add "equal to or less than sign" in addition to < or > sign.

    I can spend $80 on a cheap graphing calculator that is operating in a bygone era, or I can use this app which is MUCH more functional, intuitive and $5 to boot. No brainer.
