This is, as the title suggest, a calculator application that can do adition, substraction, divide and multiply, as well as raise to the power of 2 or any other power, change the sign of your current number and even get it's factorial ( x! ). You can download the app with calculator.exe and you can run the app with main(.exe).
I've made this app using python. The GUI was made with tkinter.
Don't allow (negative)**x, 0<x<1
