Mathematics is a powerful calculation software for your android smartphone.
Calculate any formula you want and show them in a 2d or 3d plot. The natural display shows fractions, roots and exponents as you would expect it from mathematics.
In a few seconds you derivate or integrate your desired function, calculate the zero points of your function und show them in the function plot. See all maxima, minima or inflection points in one view.
The easy way of use allows you to solve linear equations in just a moment. Or transform your mathematical, physical or chemical equation to any unknown variable.
You often needs to calculate with binary, octal or hexadecimal number systems? No problem! You can mix them together in one calculation even by using decimal digits. But that's not enough! You can also calculate with any other number system with base 2 to 18.
From time to time you may need to convert units to another one, like Celsius to Fahrenheit, miles to kilometre, inches to foot and so on.
You will also be able to calculate with vectors, matrices and determinants.
All this features are combined in this app and will make your mathematical life a lot easier.

Furthermore, Graphing Calculator by Mathlab displays calculations as it performs them on the high-quality display of the Android device, making it easier for the user to understand the calculations and see them clearly. This app has two great strengths. First, it acts as a fine scientific calculator, but, more than that, it displays the intermediate steps of the calculations as you type. It allows the students to both watch and learn how the calculations are made and how to find the final answer. Second, the graphing ability is absolutely stunning! Not only does the calculator beautifully display the graphs, but it automatically generates the x- and y- values and displays them as well.

Create geometric constructions and move, scale or rotate them with one or more fingers.
With the Freehandmode you can additional build your lines, circles, squares, rectangles and many more by drawing them on the screen. The system will detect it and create the object for you! For example, you can draw a freehand circle through three given points to create their circum circle.
Furthermore, you can create even complicated mathematical projects by using one of 70 tools to add different points, circles, lines (Perpendicular bisectors, Orthogonal lines, Tangents, etc.), conics, angles, functions and many more.
Define functions and parameter curves to display, integrate or derive them. Create analytical objects like tangents and circles of curvatures or combine your creation with sliders, text and check boxes. Even exact calculations are possible with the own FreeGeo Computer-Algebra-System, for example solving equations.
FreeGeo can be used in other sciences, too. You can do statistical calculations by using one of the regression methods to interpolate given data points. And it is a nice app for learning for school!

Q. Is there are tutorial anywhere explaining how to use the graphing calculator?
A. There are three into tutorials in the app for the calculator, graph equations, and graph screens. Additional tutorials can be found on our website http://www.mathally.com/
Q. How do I get to the keys for pi, e, solve, etc?
A. There are four keyboard pages. Each swipe direction across the keyboard moves you to a different page. The default page is the swipe down page. To get to the page with trig functions, swipe left. To get to the matrix keys, swipe up. To get to the last page, swipe right. No matter what page you are on, the swipe direction to move to a specific page is always the same.
