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. :(
