Bro lol we're both saying the same thing. The question is absolutely at fault here for not being unambiguous.
And in mathematics, an unambiguous expression is simply mathematicallly INCORRECT.
So the correct answer here is that the question is wrong

Ah gotcha. Goofy ahh formatting indeed

However I do not agree with the last statement you made since there is not one correct way to interpret it unless specified explicitly

Yes. And my (now deceased) college professor who had a double PhD and 30 years of teaching experience.
And I also went to YouTube after some people in the thread confused me and Dr Trefor Bazett has the same answer as me, that is, it's simply an incorrectly written expression.

Everything you wrote is correct and I do not disagree with any part whatsoever.

But you only explained how the expression would be treated if there was a proper use of paratheses. In this case the expression is not explicitly paranthesised which is the whole point of our discussion.

An actual mathematician would take a look at this expression and before giving you the answer would point out that you should use proper brackets. And then he'd tell you that 1 is the mathematically correct answer whereas 9 is the programmatically correct answer

If a source has concretely stated that "the correct answer is 9" then that is a bad source since the first thing a good source in this case would point out that the expression is written incorrectly.

  1. I was not educated in America. Why would you even assume that
  2. What I said is mathematically correct (even though it's different from programmatic math)

You can refer to a scientific calculator.

Google will use the programmatic definition (which is not incorrect by any means) but there's ambiguity in this expression. And the mathematical definition should definitely be treated as being the correct one in case of an ambiguity

Any real mathematician wouldn't write a stupid expression like this anyways

That is so true and is literally the main reason for the entire argument. It's not a mathematical expression if it's ambiguous and there's multiple ways to interpret it.

However the fact that people now consider 9 as the accepted answer is surprising to me but it's probably because people are more concerned with the programming aspect of mathematics than the scientific.

Math in computer programming has different conventions than academic math.
I do see your point and if you're speaking in terms of computer programming then yes multiplication and division operations are evaluated serially.

But every math textbook I have used would treat a coefficient different than a multiplier.
It's a popular argument people get into all the time about how you treat the expression a÷bc. Is it (a÷b)×c or is it a÷(bc)
And the answer is that the expression is just poorly written since it is not presented in an unambiguous way. So if you're a computer programmer I can understand why you'd think 9 but from a strictly mathematical point of view it's 1

The expression is 6÷2(1+2) and not 6÷2×(1+2)
Yes that × operation makes a huge difference. If the expression were written as the latter one, it would evaluate to 9. But since there is no × between them, it makes the 2 a coefficient of the bracket, and not simply a multiplier. And coefficients are evaluated first.

For example consider the expression "10a ÷ 5b" with a and b being unspecified constants. In such a case you will perform the 5×b operation before the division because it is a coefficient. This expression is (10×a)÷(5×b) and CANNOT be evaluated as (10×a÷5)×b

Yes the question is meant to start a war that's for sure. Regardless, there's only 1 correct answer

posted about a year ago

Yes I know what PEDMAS is. The answer is still 1 (read the expression a bit more carefully)

Again, let me know if you want me to explain it

posted about a year ago

Blud it's a mathematical expression how can it have multiple answers. There is only one correct value of the expression (like every other expression) and it's 1

posted about a year ago

No I mean 1
Let me know if you want me to explain it

posted about a year ago

1

edit : To be more clear so as to not create more confusion. The answer is that the expression by itself is simply an incorrect expression since it is ambiguous in interpretation. So for a computer programmer it is ok to say 9 bcoz in programmatic math, division and multiplication are evaluated serially
