Areo Calculator is an advanced, completely free calculator that can draw charts of all functions and calculate complex mathematical actions. Just enter actions such as (2+3.5)*88/2^2 and the program will calculate them immediately. A big advantage of the application is the option to automatically save the execution of actions and the ability to define variables that help to quickly check the results for different exponents.

Additionally, graphs of drawn functions can be freely enlarged and exported to BMP or JPG format. Areo Calculator can also calculate complex mathematical functions such as trigonometric functions, logarithms. The quality of the programme may be confirmed by the fact that it received the first prize in the 2004 Kalisz IT Competition.
