This is going to sound lame to most of the folks here, but I just finished a college algebra class. I’ve been doing database/software development/IT work for more than a decade but I have virtually no math background besides what I picked up my freshman year of high school.

I recently started working at a university so I’m taking advantage of the tuition reimbursement to build up my math knowledge. It’s a long-term project because I can only take one class a semester, but I’ll probably stay here until retirement (wife is tenure-track faculty at same university), so I’m in no rush.
