6 / 2(1+2) = 7

[mibn2cweus]

While the world argues over whether the correct answer is 1 or 9 . . . I get 7 as the answer.

So what's the problem with everyone else?

[Jackdaw33]

What's your solution, as the answer is clearly 1.

[Old_Geezer]

9
Brackets first so 6 / 2 * 3 = 9

To get 1 you need brackets around first 2 and end bracket.

I'll leave you to explain 7.

Maybe, JD33, Mibn2cweus is coming at the question from a religious or spiritual approach (given that it's in R&S), rendering normal mathematics invalid?

However, as a maths graduate who has taught the subject to A-level, I agree that the only valid answer to the question (as it has been typed) is 1.

[Prudie]

clearly 1 to me too

[Jackdaw33]

OG, 2* 3 = 6
6/6 = 1

^^^ LOL (or possibly GROAN!) at SoulofD ;-)

[Jackdaw33]

Some people seem to have forgotten BODMAS.

[Mamyalynne]

It's all Google's fault ;-)

...mathematically, it depends how it's written or printed....not the same as on here.
Six over two,then multiply by 3...or
Six over (two multiplied by three)

[Buenchico]

^^^ I was never taught BODMAS (and I never taught it to kids). I was always taught simply to read everything as sentences in English. e.g. "Six divided by the product of two and three is equal to . . . ".

I had intended to post this in Science . . . but you might have a point.

[mibn2cweus]

Since this did end up in R&S, the answer I came up with '7' seems appropriate enough, but this is how I came up with it:

2(1+2) expands to 2*1 + 2*2 therefore the problem becomes:
6 / 2 + 4 which equals . . . 7

m i right?

[Jackdaw33]

No, you are using the first 2 twice.

[mibn2cweus]

So then I have proved the 'distributive property of multiplication' . . . invalid?

[Jackdaw33]

Once you have removed the brackets you are left with 6/(2 + 4) = 1.

[mibn2cweus]

//Once you have removed the brackets you are left with 6/(2 + 4) = 1.//

But you haven't . . . . . . . . . . . . . removed the 'brackets' ^ . . . ^

[Togo]

Or is it meant to be 6/2=3 (1+2) = 9?

Or if mibn wants to formulate a theological debate

//In abstract algebra and formal logic, the distributive property of binary operations generalizes the distributive law from elementary algebra. In propositional logic, distribution refers to two valid rules of replacement. The rules allow one to reformulate conjunctions and disjunctions within logical proofs.//
Yaaawwn.

[Jackdaw33]

No, but in being left with 6/(2 + 4) you must then remove those brackets first, leaving you with 6/6.
