Prompt

I was thinking about learning math and computer science in a bottom-up, concrete and proof based method. Could you create a guide or a journey map about how to travel across this landscape. I prefer books over online tutorials unless the tutorial/video is specifically designed to be hands on learning. Lastly, if you were to start this journey how would you do this, to extract as much meaning and knowledge as possible, without any kind of superficiality.
