…says person quoting Wikipedia and NOT a Maths textbook! 😂
Yes it does., need to work on your comprehension…

You can disagree as much as you want and 3x4 will still be defined as 3+3+3+3. It’s been that way ever since Multiplication was invented.

The arithmetic operations, addition + , subtraction − , multiplication × , and division ÷
That better? Or you can find one you like all by yourself: duckduckgo.com/?q=binary+operator&ko=-1&ia=web
And you can shove the condescension up your ass until you understand the difference between unary and binary operators.
But to original point. I’m not disagreeing with anything and you’re proving my point for me. There is no fundamental law of the universe that says multiplication comes first. It’s defined by man and agreed to. If we encounter aliens someday, the area of their triangles are still going to be half the width times the height, the ratios of their circles circumference to diameter are still going to be pi, regardless of how they represent those values. But they could very well prioritize addition and subtraction over multiplication and division.

Is it a Maths textbook?
I already have dozens of Maths textbooks thanks.
It’s not me who doesn’t understand the difference.
Still need to work on your comprehension then. I did nothing of the sort.
Yes there is. The fact that it’s defined as repeated addition. You don’t do it first, you get wrong answers.
It’s been defined and man has no choice but to agree with the consequences of the definition, or you get wrong answers.
No they couldn’t. It gives wrong answers.

Actually, it is. With by a PhD and used in a college course. It just happens to be distributed for free because Canada is cool like that.
May want to work on your own reading comprehension.
The facts disagree.
You can keep saying defined all you want, it doesn’t change the underlying issue. In the absence of all your books (which you clearly don’t understand anyway based on our discussion of unary vs binary) order of operations only exists because we all agree to it.
