We learned about it in year 5.
Order of operations was basically the first thing we were taught in 6th grade.
4th-to-6th here
Order of operations was like, chapter 1 of my algebra book, before it even told you to solve anything.
Fourth grade here. We started with "do whatever's in parentheses first", then gradually expanded that to "but if there are no parentheses, here's what you do."
'Point before line' (i.e. multiplication/division before addition/substraction)... hm, as soon as we had calculations with more than one operation, or at best only a little bit later. 2nd grade actually I think. Parentheses in fifth grade then.
We learned about the order of operations, parenthesis included, back in 2nd grade.
Now that I think of it, we were evaluating some slightly complex expressions before algebra, so I had to have learned it earlier, but hell if I know when.
I actually have a great-aunt named Sally...

The mnemonic orders addition and subtraction? That's just weird. I mean, mathematically it doesn't matter, but surely it's making everything even more complicated... and, as I see on wiki, multiplication and division are ordered, too...
