6÷2(1+2) equals what exactly

So, precisely what the thread title is asking. What exactly does 6÷2(1+2) equal

Nobody seems to able to come to an agreement on this. So, as you lot tend to be a bit smarter than the average bear, I'll let you have a go.

There are 3 options in the poll so just vote for the answer you got, and we'll see where the majority lies.

Re: 6÷2(1+2) equals what exactly

No poll.

I got 9
6/2 = 3
1+2 = 3
3 x 3 = 9.

EDIT: Ah, there it is...

Re: 6÷2(1+2) equals what exactly

Brackets first, then multiplications/divisions, then addition and subtraction. So I say the answer is 1. But then I got kicked out of Swiss school for being so spectacularly sh*te at maths. Thankfully the British system thought my mad maths skills worthy of a B in GCSE...

Re: 6÷2(1+2) equals what exactly

You must apply the 2(1+2) first, it cannot be separated.
That bit is 6.
Any number divided by itself is 1
6/6 =1

If at a dinner party you guys need to get out more.

Unfortunately you are wrong. The original of this equation should be like:
6÷2.(1+2). You can also put the "x" instead of "." When you have this it's clear: division is always done first. Now you can find the 9 result.

But do you do multiplication or division first?

I think it can be either 1 or 9 depending on how you were taught order of operations

You do multiplication first. Therefore, it's 1.

BODMAS
Brackets first
Orders (ie Powers and Square Roots, etc.)
Division and Multiplication (left-to-right)
Addition and Subtraction (left-to-right)

=9 (also the answer Excel gives )

Divisions and multiplications rank equally, so you go left to right in order of appearance.

Re: 6÷2(1+2) equals what exactly

I got 9. You do all calculations left to right, except brackets are first. Then you do any multiplications and divisions in the order they occur left to right. Then you do any non-parenthetical additions or subtractions in the order they occur, left to right. If there were exponents, you'd do them just after the brackets.

I might be wrong, but I've never heard of UtH's "can't be separated" explanation - a number abutting the parenthesis means "x"/multiply.

I'm pretty sure you do whatever comes first in the sum first.

So you do the brackets (1+2) which is 3

Then the division because it comes first looking from left to right so it's 3 x 3 = 9

A(B+C)= AB+AC
The A next to a parenthesis equals multiplication. Hence you need to resolve it. The fact that no multiplication sign is present seems to confuse most.

UtH is right.
See spoilers up for details.

Re: 6÷2(1+2) equals what exactly

For the South Africans out there, remember BODMAS, not a word that makes sense but one I have never forgotten, I wonder if they still teach it like that.

Brackets
power Of
Division
Multiplication
Adddition
Subtraction

Therefore the South African answer is 1
