Thought you might be interested - I just finished the first two videos of the Stanford University course Introduction to Mathematical Thinking by Keith Devlin.
It's surprisingly interesting from my non-math perspective. The course tries to bridge the gap between K-12 rote math and "real world" math and calculations.
I'm not far into the course yet, but so far, I'm finding it interesting.... which means it's likely WAAAY too basic for you, but I am coming from a place where I use to have a disdain for math.
