Yeah, I am always the first to admit I learned something ... which most consider a detriment to themselves.

I just don't understand say if

2*4(3/4*2(14+2))5+6/(34/8.5)/2=?

What happens? Maybe I am thinking too hard.

yep, ur thinkin too hard cause that is an incomplete equation to start with but you would work it from the inside, out rather left to right.

It is operable... it just has more than one set of divisible subsets. I may have complicated it but what would happen when there is more than one divisible subset in an equation?

it's 9. it can't be anything else.

in an equation, you can move things from side to side to test your answer and working. so you change the first line to be:

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

? == 9

Done. Close thread

I say damn the maths, I'll go with 10 = it is both answers combined, can't go wrong!

... damn thread made me remember how much I hate maths...

I wish i was still at school, i would write this equation in the middle of the white board in huge text and let the whole class fight over the answer

well i put the answer as 1, but about 1 million people aregue that its 9, apparently If it were 6÷(2(1+2)) it would be 1

so i just wanted a definitive answer.


The answer is 9 IMO, and I have a really bad grade in maths lol

The answer is 1

Not 9......... 1

It shamed me to hear an engineer student ranting that it is 9. I'm an engineering graduate and I'm telling you its 1

Type it in to ANY DECENT calculator (not Google) and you will get 1





If you don't get it that's fine, but please stop slamming people for trying to correct you.

But I just google the answer, and the answer is still 9.

6/2(1+2)=....

First you deal with the brackets

1+2=3 hold onto the 3 cos you need it later....

Then you divide 6 by 2=3.....

The 3 from (1+2) and the 3 from 6/2, now sit side by side like this .... 33, which is the same as 3x3

3x3= 9

The answer is 9. I may have a poor mathematical background, but seriously, this is the answer, unless of course the whole of GCSE Maths is now wrong, in which case, I don't feel so bad for having such a poor outcome in my exam

Ok how do you even get 1 ???

What rules are being applied here ?

EDIT: scrap that now I see how people are getting 1.

And its just not possible, unless there is more than one rule that can be in play when solving the sum.

was always taught brackets first.

WhoTF decided to put the extra bracket in, that isn't in the original sum, the sum is...

6/2(1+2)= .... there is only one set of brackets, and they relate to the 1+2 portion.

Can see why OP was confused

There is no extra bracket used

Look at my calculators and tell me where you see an extra bracket?

Dude who's talking about your sum, god complex much ?!

If you go back to my first reply, you will see I refernce the OP, not you, so cool your heels.

Second I haven't even read the conclusion you came to, because SHOCK HORROR ! I haven't read the entire thread, just the gist, understandable given that I am not a troll !

Nothing wrong with a bit of healthy curiosity, oh and while I'm on it, don't know what country youre from, but perhaps this is a cultural issue, as from where I come from this is how the sum is solved.

Calculating it in my head game me a nine, wasn't satisfied till I pasted it into google & got this 6÷2(1+2)=9 ...

Sorry, I'm not trying to bash you, was never my intention.

I guess your in the UK due to you mentioning GCSE's

I'm in England and this is definitely how it is taught.

Any way I'll be quiet now, I've said my piece

I thought it was:

6 devided by 2 = 3

Then 3 x (1+2) = 9

Surely that is correct?

I have one calculator that gives 1 and one calculator that gives 9.
Specs: TI-83 Plus: Equation: 6/2(1+2) = 9
Specs: Casio fx-300MS: Equation: 6/2(1+2) = 1

And I always complained that my Physics and Calculus Profs wouldn't let us use calculators!
Ha! Guess they wanted us to think for ourselves, or some drivel!

Or perhaps a ploy via the machines?? -> Induce human insanity slowly but surely by making them question the very fundamentals of their early educations! Evil calculators!

Dammit, now I am confused


6 divided by 2 x (1+2) is indeed 1.

I just retook my maths GCSE last year, I should bloody know this!
