Was anyone else ever taught it as BOMDAS as opposed to BODMAS?

Why do people put bot pairs of multiplication and division, and addition and subtraction on the acronym?

Do you really follow that order with the associative operations?

Because it's intended to be used as a checklist

Yep

I think so. Amazing how many different ways there are to say it

So instead of Parentheses, Exponents is it Box and O that digit in the sky?

Brackets and Orders, not that anybody calls "(" a bracket or "^" an "order".

It's "to the order of" actually. 2² is 2 to the order of 2

not that anybody calls “(” a bracket

Yes we do. They're ALL Brackets - square, round, squiggly...

They're all just different mnemonics for the same rules.

It was BEDMAS for us, where the E was exponents or something.

There's no difference.

Addition and subtraction are the same operation, multiplication and division are the same operation.

So:

BO(MD)(AS) == BO(DM)(AS)

EDIT: in order to stop confusing people, it should just be: BOMA.

No they're not, but they are both binary operators.

in order to stop confusing people, it should just be: BOMA.

Leaving out D and S confuses people about where to do them in the order. It's intended to be used as a checklist

Where you, yet again, ignored that I told you what you said is wrong, as per Maths textbooks

Yeah, I was taught BOMDAS here in Australia.

BODMAS (or BEDMAS), not BOMDAS. (unless they did that in some random state). I'm an Australian Maths teacher

Or it was some random teacher. Or it was more than fifteen years ago. I dunno, it was just what I was taught.

Yeah, maybe. My Year 7 students, who have come fresh to me from Year 6, use BEDMAS, and I teach BEDMAS for consistency (I also think it's a better acronym anyway - think of a massive 4-poster bed to ingrain the idea of BED-MAS)...

I was taught only Brackets Division Subtraction Multiplication at the local dungeon.

(I still have the student loans to prove it.)

[–] essell@lemmy.world 2 points 9 months ago*

Its BODMAS for maths and BOMDAS for twerking.

Easy mistake to make given the amount of maths involved in dancing.

I don't think so, and I've seen Maths textbooks from all over the world. Only the U.S. wants to reverse the order of DM from everyone else's acronym. 🙄
