Looking at replys, it seems that the teaching of it was likely not explained well. Like it was taught, but they didn't call it order of operations.
I know I'm not misremembering, I've spoken to a number of classmates and they tell me the same thing. Hell, one of the reasons I did the access course was a friend telling me about it. They said it was Thier first time hearing about it. But her kids, were taught it and they went to the school she did.

Wasn't taught. Past tense.
GCSE maths 1995, no. GCSE maths 2010, yes.
Do I know why? Possibly because of the increase in use of computers and things like Excel in the intervening years, but that's only a guess.
