As a backend programmer I use it all the time. As an example I use it to determine percentage of total. I use it for discounts and taxes regularly. Figure totals of an order.

I guess some things just stick for some people and not others.

I can recall the order of operations from school. Can’t remember peoples name though. I left school in 1999. For some reason I’ve never forgotten all the damn bones and muscles in the body either but I only did anatomy and physiology for a year and now I’m a software engineer. Minds are weird.

I haven't had to do this shit in 20 years since college. Literally nothing like this in my career path, I was shit at math in high school and college,, so I didn't even remember that there was a multiplication there since it isn't explicit. Oh well.
