Hi sirsinalot, I wrote a book that might be of interest to you: https://nobsmath.com/ = math for adult learners

Here is a PDF preview to get an idea of the contents: https://minireference.com/static/excerpts/noBSmath_v5_previe... and a standalone printable concept map: https://minireference.com/static/conceptmaps/math_concepts.p... There is A LOT to learn, but I assure you that as an adult you can understand the material much more easily, especially with our background in computing now.

I highly recommend you try rekindling your relation with math one day. It has lots of knowledge buzz moments, when you see things fit together. Feel free to email me if you have any questions, or you can post them on this forum for readers of the book https://gitter.im/noBSmath/community
