A “teacher” who doesn’t know that all lessons are simplifications that get corrected at a higher level,
As opposed to a Maths teacher who knows there are no corrections made at a higher level. Go ahead and look for a Maths textbook which includes one of these mysterious “corrections” that you refer to - I’ll wait 😂
refers to children’s textbook as an infallible source of college level information
A high school Maths textbook most certainly is an infallible source of “college level” information, given it contains the exact same rules 😂
A “teacher” incapable of differentiating between rules of a convention and the laws of mathematics
Well, that’s you! 😂
A “teacher” incapable of looking up information on notations of their own specialization
Man, this whole post has been embarrassing for you. Oof.
I can’t help but notice youve once again failed to address prefix and postfix notations.
And that you’ve not actually made any argument other than “nuh uh”
Not to mention the other threads you’ve been in. Yikes.
Your argument you haven’t made is backed up by math textbooks you haven’t provided written for children.
What is it that you want addressed?
How can that specific order of operations be a law of mathematics if it only applies to infix notation, and not prefix or postfix notations? Laws of mathematics are universal across notations.
Show me a textbook that discusses other notations and also says that order of operations is a law of mathematics.
You don’t have it, and you also aren’t a maths teacher, or a teacher at all. Just because you say it a lot doesn’t make it true.
Your argument you haven’t made is backed up by math textbooks you haven’t provided written for children
That’s quite a word salad. You wanna try that again, but make sense this time?
Your argument you haven’t made
If I didn’t make it then it’s not my argument, it’s somebody else’s 😂
is backed up by math textbooks you haven’t provided
as well as the textbooks I have provided 😂
written for children
All my textbooks are for teenagers and adults

I already addressed that here. I knew you were making up that I hadn’t addressed something 🙄
Laws of mathematics are universal across notations
Correct, they do.
also says that order of operations is a law of mathematics.
If you think it’s not a Law, then all you have to do is give an example which proves it isn’t. I’ll wait
You don’t have it
You mean you don’t have a counter-example which proves it’s not a Law
you also aren’t a maths teacher
says liar
Just because you say it a lot doesn’t make it true.
You know you just saying it’s not true doesn’t make it not true, right? 🤣🤣🤣
BTW, going back to when you said
8÷2x4 PEMDAS: 8÷2x4 = 8÷8 = 1
Here it is from a textbook I came across this week which proves I was right that you did it wrong 😂
Therefore, doing Multiplication first for 8÷2x4 is {(8x4)÷2}, not 8÷(2x4) - whatever you want to do first, you write first - exactly as I told you to begin with 🙄
Left to right is a convention, yes, doing Multiplication and Division before Addition and Subtraction is a rule 🙄
A claim entirely unsupported by the textbook example you provided. Nowhere does it say that one is a convention but not the other, it only says that removing brackets changes the meaning in some situations, which is fully within the scope of a convention.
For the 3rd time it does have order of operations 🙄You just do them in some random order do you?
There you go again, just admitting you don’t know what postfix and prefix notations are.
If you’re ordering your operations based what the operator is, like PEDMAS, then what you’re doing isn’t prefix or postfix.
I’ll tell you what, here is a great free article from Colorado State university talking about prefix, postfix, and infix notations.
Note how it says the rules about operator precedence are for the notation which itself is a convention, as all notations are, and how prefix and postfix don’t need those rules
says person who doesn’t know the difference between conventions and rules, and thinks postfix notation doesn’t have rules 🙄
How embarrassing for you.
Here are some more materials:
Plus dozens of Quora answers, articles from online academies and learning centers, that I figured you’d just dismiss.
But to top it all off, if this was truely a law of mathematics, then show me a proof, theorem, or even a mathematical conjecture, about order of operations.

Our friend doesn’t know what a mathematical proof is, and will instead try to give you an example in which he posits a real-world calculation, writes down an arithmetic expression for it according to one convention, interprets it with another, gets a different answer, and tells you this is “proof” that it’s wrong.
When I explained to him how you could write down the expression according to a different convention, then interpret it with the same convention and get the same answer, he just denied, denied, denied, with no sign of understanding.
Strange that this way of assigning meaning to a string of mathematical symbols is a convention then, but not the other part that is mentioned in the same paragraph 🤔🤔🤔

We can all tell you’re not a maths teacher.
Nope. I’m the only one who has backed up what they’ve said with Maths textbooks 🙄
What is it that you want addressed?
Backed up by Maths textbooks 🙄
Says person who actually isn’t a Maths teacher, hence no textbooks 😂

In your screenshot of a textbook, they refer to it as a convention twice.
And you still haven’t explained prefix or postfix notation not having order of operations.
Get rekd idiot

For the 3rd time it does have order of operations 🙄 You just do them in some random order do you? No wonder you don’t know how Maths works

That screenshot calls it a convention you troll.
says the actual troll, who didn’t notice it was talking about left to right,. which is indeed a convention which it is explaining 🤣🤣🤣
