6 is one expression.
2 x 3 is another, as it originates from 2(1+2) which is also ONE expression.
It's 1.

BODMAS?
define the bits please
I recall learning
Bless My Dear Aunt Sally
brackets multiplication division addition subtraction
when did it change M and D?
I always assumed they were equal, and therefore done outside of brackets, should be done from left to right

it's not confusing, you haven't finished expanding the brackets until you've completed the multiplication of the contents...
it's actually 6/((1+2)+(1+2))
No operator means multiplication
The amount of confusion on here is crazy for one of the most basic sums possible
No it doesn't, they're treated equally, so in that case you'd simply go left to right and end up with
6 / 2 = 3
3 * 3 = 9
Maths doesn't work like that. You always do the brackets first...
huh? The brackets were first...
6÷2(1+2)
Hence I said firstly 1+2=3

yes...and until you do that step you've not finished with the brackets ergo that step comes before the division of 6 by whatever the bracketed part becomes.
Oh okay. Didn't know you simply go left to right as a rule.
You appear to be talking out of your backside.
If you had 6/6+(1+2) you wouldn't work out 6 + 1 + 2 and divide 6 by that whole amount, which seems to be what you're suggesting.

I would have gone with 1, but according to the rules that is wrong...
I think the issue is using a division sign, who uses that if they're above 12?

?Bidmas is clearly fallible if people are justifying an answer of nine with it.
6÷2(1+2)
6 is ONE term.
2(1+2) is ANOTHER term.
In order to achieve a result of 9 you would need:
6(1+2)÷2
It is entirely possible this problem was introduced to highlight the flaws of the BIDMAS rule.
