HiPER Calc Pro

Excellent scientific calculator with step-by-step solutions, symbolic algebra, graphing, equations, integrals and derivatives.

The calculator has globally more than 50 million downloads and 250 000 five-star ratings.

You can write expressions in a natural way and watch your calculations. The result is displayed as a number, simplified expression etc.

An expression can also be entered from a photo. Take a picture of a handwritten or printed expression, and the calculator recognizes it and inserts it into the display, ready to be edited or evaluated.

A step-by-step solution shows how an expression is solved, one step at a time, from the entered expression to the final result. Every step is explained, so you can see not only the result, but also the way to it.

Calculation details give you extended information about the result - alternative forms of the result, all complex roots, the unit circle, properties of a function and more.

The calculator has several layouts suitable for various screen sizes:
- "pocket" for small devices
