A free, powerful scientific calculator. with no ads on the main screen.
This free scientific calculator, with no advertising displayed on the main calculator screen, offers a comprehensive set of useful features allowing you to carry out advanced calculations. Its simple and intuitive design makes it a pleasure to use. The calculator has all the functions that would be expected of a scientific calculator and a number of advanced features allowing the calculation of complex numbers, vectors, matrices and statistical results. The calculator also includes a graphing function, in equation mode, allowing up to 4 equations to be drawn on the same graph. The graph can be both scrolled and zoomed.
The calculator is customizable allowing you to change the colors of the screen, background and all the individual buttons, allowing you to personalize its appearance.
An ad-free version of this App is also available.
