  Very confidently getting basic facts wrong doesn’t inspire confidence in the rest of your comments.

  …says person quoting Wikipedia and NOT a Maths textbook! 😂

  Your example still doesn’t give a reason why 2 + 3 * 4 is 2 + 3 + 3 + 3 +3

  Yes it does., need to work on your comprehension…

  Multiplication is defined as repeated addition - 3x4=3+3+3+3

  other than that we all agree to it

  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

    Yes it does., need to work on your comprehension…

    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.

      you’re proving my point for me.

      Still need to work on your comprehension then. I did nothing of the sort.

      There is no fundamental law of the universe that says multiplication comes first.

      Yes there is. The fact that it’s defined as repeated addition. You don’t do it first, you get wrong answers.

      It’s defined by man and agreed to

      It’s been defined and man has no choice but to agree with the consequences of the definition, or you get wrong answers.

      But they could very well prioritize addition and subtraction over multiplication and division

      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.

        The LibreTexts libraries are Powered by NICE CXone Expert and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program

        May want to work on your own reading comprehension.

        It’s not me who doesn’t understand the difference.

        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.
