since when?

288... pretty bloody easy really..... unless you're a retard.

This fixes your amateur mistake how? Also there is only one person in this thread claiming to be a real success story.

2*(9+3) IS THE SAME AS 2(9+3)

What if the person who wrote the equation intended that;

48 is the numerator and

2(9+3) is the denominator?

Because of the limitation of writing the equation as a single line blurs the intention of the equation making it open for interpretation.

Come now lads, this may lead to behaviour not worthy of a gentleman.

In that case they should have written the equation as 48/(2(9+3)).

I just want some clarification, I'm okay with being proven wrong, but I'm not seeing any proof

...and I'm not a lad...

I know you're not a lad Sarah. And I've learnt not to suggest any sort of behaviour-modification to women, as the scars take much longer to heal these days, so that hideous remark wasn't aimed even vaguely in your general direction, but rather at the rams butting heads ....

Some opine (including myself) that the term explicitly to the left of the brackets is an operation on the brackets given that there's no * between the 2 and the (. That's certainly what I was taught and had read as a rule (no idea what's taught now as that was ~30 years ago).

Hence, 2(9+3) is explicitly 2 times the contents of the brackets. It is a singular function and should be treated as such.

So, what rule did the original mathematician follow?

it IS the equation, because NO operator between a number and a bracket means Multiply! The X is redundant, whether it is there or not, the answer is the same.

Nine pages is pretty good - the piston fella's got 20 odd though...we have a long way to go...

Yes, that's what I learnt too but couldn't express myself.
But I caved and said 288 to stop the kids yelling.
Doesn't appear to have worked.

[SteveJH]

I calculated 2 the first time I did it then changed my mind and said 288 once i put it into excel and thought through it some more.

In the end I just figured that if they wanted the answer 2 they'd have been explicit and said 48/(2(9+3)).

Eitherway, it aint the most well written of equations.

Search 48/2(9+3) on Youtube.

Edit: My calculator says two, and it hasnt failed me yet, so 2 it is. *shrugs*

[Stefan]

By taking away the multiplication sign before the bracket generally indicates and intimacy of the numbers and it is generally accepted that they are given precedence in the operation of the equation. The answer is 2.

i didn't bother reading very far into this thread.
thought id reply to this comment and say that i can count up to 1023 using just the fingers (and thumbs) on both of my hands.

I've never had to go much further mentally in binary but i guess it is possible for a man to count to 2²¹

Does 48÷2(9+3) have a facebook page already ? Is it seeing anybody ? Will Will dump Kate for it ? So many questions, so little interest.

Four of them popped up on the first page of the search results.

There are 10 types of people in the world.

Those who understand binary and those who don't........

2²¹ -
I was trying to work it out on my toes but came up with 2 097 152.
This can't be right - will I get an ingrown toenail now ?

That's some funny stuff right there.

i might have been slightly incorrect with 2^21. but if you use 21 "fingers" (10 fingers, 10 toes and 1 *****) you can get a binary number of 00011111 11111111 11111111
.. ill leave it as a "big number" .. much higher than 21

a big number had something to do with this I suspect -

Any elements in brackets should always be calculated first, followed by multiplication, division, addition, and subtraction.

Assuming the correct equation is 48÷2X(9+3) it must be calculated this way

Brackets first: 48÷2*12
Multiplication next: 48÷24
Division next: 2
There is no other way to calculate the above equation correctly under the following mathematical principal

there are no grey areas here there is only 1 correct method of calculating a mathematical formula

THE ANSWER IS 2

of course there is a different answer if you think a bit differently
48÷2X(9+3)
Brackets first: 48÷2*C
Multiplication next: 48÷18
Division next: 3
