6÷2 (1+2) = ___

[9 Nines]

You are in El Paso and travel to New York City.  A train takes 3 days 4 hours. A car takes 2 days 3 hours.  A plane takes 6 hours.  If you take the plane but look at the train, while driving a car, how long does it take you?

It takes me 4 burritos.

1 final answer 

 

Granted the division sign could be fucking me up. I'm assuming it's basically saying 6/(2(2+1)) but that could be wrong.

 

If it's essentially (6(2+1))/2 then it's 9.

 

Edit: yup. It's 9. The other group of parenthesis aren't implied.

You bunch of imbeciles. All of you. The answer is so painfully obvious.

 

 

 

 

See? Even 9 knows it's 1.

1, in 6/2(3) the implied operator takes precedence.

Hey FistShaker, 9 was just slightly smarter than you, which by the way isn’t saying a whole hell of a lot. He apparently got some pussy though and we all know how that worked out. What happened this afternoon? Mom have to take a flamethrower to your bathroom?

The implied operator is multiplication, not division.

Yes, so 2(3) takes precedence, so then the equation becomes 6/6 .

Parenthesis first, then exponents (there are none), then division/multiplication from left to right. 6÷2 = 3(3) = 9.

I disagree. Implied operators come before known operators.

Its 9. There is no other answer.

He's right. It's 9. There's a reason engineers don't use ÷ though. Typically people write it as a fraction to be clearer.

That's the thing with this equation. I think it was written vaguely on purpose to stir up debate. I've seen debate about these equations in other places as heated as a debate about politics or religion. Which is just further proof... people will disagree and argue about anything, even if it's a boring ass math problem from 4th grade, if they feel their ego has come down with a case of butthurt.

The thing is this is easy enough to test. Put it in a calculator as written. That's how I found my mistake. If this was in a professional setting though it'd be written differently.

 

But yeah people will argue about anything especially online.

Yep. Math, in and of itself, is not ambiguous. The ambiguity in math is the ambiguity people leave behind. Math can be complicated, but complicated and ambiguous aren't the same thing.

 

Google calculator immediately outputs this as 9. The calculator at this site https://www.desmos.com/scientific writes it as a fraction and automatically places the (2+1) at the bottom of the fraction, thus getting 1 as the output. But if you move the cursor up to the middle part of the fraction you get 9. That's actually the best visual representation of the debate that I've seen. People who are getting 1 as the answer are multiplying the sum in the parenthesis by the denominator in the fraction whereas the people getting 9 are multiplying the fraction, or rather the sum of dividing the numerator by the denominator, by the sum in the parenthesis.
