Who has read this book? I’m trying to get back into maths. Last time I studied maths was when I was 16 and although a lot of the fundamentals are still there, a lot has been forgotten.

Anyone have advice for those getting back into maths?

Not sure if it's what you're looking for, I've been getting deeper into the maths lately and I started working my way through this yesterday.
