Add "ALL" Option for Randomized Operation Selection
Description
This update adds an "ALL" option to the math trainer, allowing users to randomly practice all operations (addition, subtraction, multiplication, and division) in a single session. When "ALL" is selected, the trainer will randomly pick an operation and return its type along with the generated operands. This feature enhances the variety and challenge level, supporting a more dynamic learning experience.

I think only randomizing the operator (without adjusting the number of digits) will lead to problems that are too hard or too easy.
