Hi i have a python program project

its to make an arithmetic program with difficulty levels

-essentially a calculator - that throws out addition, subtraction, multiplication, division and combined math problems at random (depending on which function the user chooses)

-also has three difficulty levels, which can be chosen by user - more digits are added when difficulty is increased

- ideally meant to have a button made in graphics - that allows the user to quit at any time and return to the main menu which allows them to choose which function to practice

and i have NO idea how to do it! only vague things, which don't help at all. please help i'm in dire straits!
