I was taught the same multiplication/division for 3 years straight.
I did have a section on those 3 M's in math, but it was a small part of the curriculum and over in a flash. I recall nothing of value.
Except the mean which came back up extensively in G10 Chem and that was it.
Watching my younger sibling do math was even worse especially when they transferred to online and a lot of the questions were actually wrong... which was a great exercise in learning, but... ugh.
Sorry friend, but not in any meaningful way as far as I'm aware. :(
IME, most people I have met have never learned, or at least committed to memory, any of these terms, or (most likely) not the concept of their specific value to analysis.
This is the one that always gets me. When we're specifically talking about the middle class, median means a whole lot more than the mean of the national wage.
