Helping with maths

So here is the story in short I have a young family member who struggles with maths so I wanted to try and make this as fun as possible. Below are the C++ project files. At the moment it’s simple maths however I will be making settings that will allow you the parent to set the difficulty. I will also be implementing an automatic difficulty setting which is linked to the score. The plan is once the score reaches 20 it will increase a level.

Now I am aware that no child wants to answer questions in a terminal so I will be creating a UI for it over the coming weeks. Anyway as promised here is the code:
