But... he's right

This is why PEMDAS should be a writing order and not a solving order.

PEMDAS works fine as long as you learn it right. People who only half paid attention while learning it though use it wrong.

Or it's because it's brought up once, if at all, and then never mentioned again. I forgot it existed all the way through high school and I was in the highest math classes.

If you weren't using it correctly you should have gotten your answers marked wrong, at which point you should have asked the teacher why they were marking your answers wrong. I remember spending a decent amount of time on it though. I don't know what they do nowadays.

I'm starting to think this is a generational thing and it was largely ignored in schools for a time for whatever reason, how old are you? I'm in my early 30s

Around 30. I've seen some work sheets from more modern classes and they seem to focus way too much on trying to teach kids shortcuts, to the detriment of other stuff. And the questions are usually phrased in extremely confusing ways, worse than what kinds usually hate with word problems.

There is no x in the equation you silly nigger

He didn't show his work. Just writing the answer isn't enough.

Showing your working on something as trivial as that is nothing more than busywork and teachers lashing out at children in a sick and fucked-up power fantasy.

>t. didn't show his work

It's to show you understand the logic of why the answer is 12. It's a "it's about the journey, not the destination" kind of thing.

He didn't show his work.

what's with all of those god damn acronyms anyway? PEMDAS, BEDMAS, whatever else. is that how they teach it in the US? just memorizing shit seems like a terrible way to learn the basics of math.

Nobita it's fine I've got an invention for this. It's called whiteout.

How else do you learn order of operations if not through memorization? BEDMAS is from England though I'm pretty sure. It's not just an American thing.They also teach you multiplication through memorization, though probably much differently than they used to. I don't really remember that far back in my math education.

Pemdas is an acronym like NASA to help you remember which order to do the maths.

Smartass, I chuckled

Wait, would this be wrong?

You just do it without any acronym, there aren't that many. Paranthesis, exponents, multiplication/division, addition/subtraction. That's four operations you learn in several years. At first you just calculate from left to right with a note that it changes a little later on and then in 5th grade or whatever the teacher tells you about multiplication/division coming before addition/subtraction. Also paranthesis before anything duh.
And then you get at least a year to get that shit down. I still have no idea how people can forget so much if they learned it over the course of 10+ years. But then again, many just shut down as soon as they see numbers because oh no numbers.
