Project to calculate Mod-n inverses
I made this for a High School Specialists Maths investigation which went into Matrices through encryption/decryption, requiring inverse Mod-n numbers.
Versions 1.4+ have a Graphical User Interface.
Version 1.5 contains 2 variables near the top of ModInverseFinder.py for developer debugging, so replace their values with True as required.
If you don't wish to download and install Python (https://www.python.org/downloads/) then if you go to https://www.online-python.com/ and upload ModInverseFinder - online.py you will be able to run the program.
