This sounds more of a regional problem more than a math problem to me -

Americans are taught our own math - we use inches, feet, yards, and miles and we're taught PEMDAS

From what I can take, majority use the metric system - nanometer, millimeter, centimeter, meter, kilometer and are taught BIMDAS or BIDMAS whatever.
BIDMAS and PEMDAS are the same thing afaik, I think the issue is more of how you look at the problem

Here's how most Americans look at it

6/2(1 + 2)
6/2(3)
6/6
1

We do the 1+2 first as PEMDAS states do what's in the parentheses first, and then distribute the two as PEMDAS states multiplication before division. Then, you divide 6/6, and get 1.

Now what I'm taking from this is other people are doing this

6/2(1+2)
6/2(3)

Now here's the interesting part. Instead of distributing, they divide and get 3(3). They THEN distribute and get 9. BIDMAS would make sense as division is put ahead of multiplication, making the distribution last instead.

Incorrect, it is in fact 9.

We aren't taught to work from left to right. Whatever you're looking at, it's not the PEMDAS millions on millions are being taught in the United States currently. We're taught to apply those same rules of PEMDAS throughout the entire equation

Which is that when you have both multiplication and division, you work from left to right. I don't understand your argument.

This doesn't exist in America, is that a little bit easier put?

What?! The order of operations doesn't exist in America?!
No. You're implying when it's just multiplication and division you work left to right. That does not happen. We still do Multiplication and then the Division.

No, no you don't. I don't know where you went/go to school, but do a little research please.
Done a quick search to realize that's not the case, I guess it may be something with my district or state because I've literally done that this whole time and not got a single problem including this kind of math wrong on a test or quiz :rofl: You win

Thanks mate. You're actually the first person I've been able to convince lol. Props for being open-minded.

That's because I'm not ignorant, if I'm wrong I'm wrong

Why is this a debate? Wolfram Alpha exists for a reason...and so do CAS calculators.

I'm from America and I distributed before division at first but when I thought back to the basics of PEMDAS, I realized that distribution is not considered parentheses so there is no reason it should come before multiplication/division. The main issue here is that 2(3) could be seen as one term because there is no operation sign separating 2 from 3. Obviously, everyone knows to multiply but it's a grouping issue. Is it (6/2)(3) or (6)/(2(3))? I could be wrong but I don't know of any rule saying to treat 2(3) as one term so I treat it as 2*3.

I learned MD and AS are done left to right. You don't do multiplication before division or division before multiplication. You simply solve in the order that the expression is given in, left to right. Same for addition and subtraction.
