Division, Multiplication, Addition, and Subtraction
This is fucking so many people over… It should be limited - like Orders - to only Multiplication and Addition.
Because division is the same operation as multiplication, and subtraction is the same operation as addition, and they have the same “weight” in the order of operations (meaning, you do them left-to-right).
Because you don’t want people to know when to do Division and Subtraction? 😂
Because division is multiplication, and subtraction is addition.
No it isn’t, but they are both binary operators.
2/2 is the same as 2*½
2-2 is the same as 2+(-2)
And where are they going to do Division and Subtraction in the left to right if you’ve left them out? 🙄
Well, as I already said multiple times: Division = Multiplication and Subtraction = Addition, therefore they would be doing them together, left to right. As in: 9-3+2 would not confuse anyone who learned “Addition → Subtraction”, as it does right now.
You got that the wrong way around. Brackets have only been used in Maths for a few centuries now
How is that “having it the wrong way around”?
What does that have to do with the topic at hand? We’re talking about maths today, not centuries ago.
And you were wrong every time you said it.
No, they’re not.
Not if you left them out of the mnemonic and they didn’t know when to do them
Mnemonic without understanding what you’re doing doesn’t help. Which is why people get confused and argue online that you must do addition before subtraction, or the other way around, depending on what the mnemonic they learned was.
Understanding that subtraction is just the addition of a negative number solves this problem.
PEMDAS bitches.
I never ran into PEMDAS while growing up, in Sweden I’ve always been taught of it as the following order of operations:
e: Wanted to see if this is a thing in English.
Please Excuse My Dear Aunt Sally… bitches.
It’s interesting that you can somewhat tell where you are from based on this, I learned it as BODMAS
O - oxponent?
To the Order of. 2² is 2 to the order of 2
Orders.

And you still have to do both
They’re equal in value, they’re not the same

Yes, it is.
Quote the part where I said you didn’t.
They are the same.
No, they’re not.

Another commenter mentioned something similar, how they’re interchangeable, but I’m not sure why you say it’s fucking people over.
