i bet 9 is correct
6/2(1+2)
1st do (1+2) so is 3
then
6/2*3
6/2=3 and 3*3 = 9
-
1st one, once () is done, its divisions order.
seems like they have different settings tho.
-
1 is correct
calculators should count it like this: (http://i.imgur.com/XIhXl.png) = 1
the calculators in the first picture is wrong
-
But if you think 6/2 as a fraction and then that fraction x (2+1), the result would be 9
-
definitely left one

u know nothing about algebra...
-
That's how i see it...
6/2(1+2)=
6/2= 3
3(1+2)= 3+6 = 9 ...

nah x equals to (x)/(y), not x/y, therefore this cant be converted.
y
and calculators don't do them like that, they do it strongly sequential, meaning it will never put () if its not specified/needed.
don't forget that if priorities are equal(which is the case with division and mul), there's mathematical law to take leftmost expression first.
-
1 is correct
It is definitely 1! Dont think its 9, that is just a lie!
Other example:
2(1+2) = 2x1 = 2 , + 2x2 = 4 , 4 + 2 = 6 --> 6:6 = 1 !
2(1+2) = 2 x 3 = 6 --> 6:6 = 1 !
-
youre forgetting that 2(1+2) is the same as 2*(1+3) the lack of * doesn't change any of the orders.
-
2(1+2) = 2x1 = 2 , + 2x2 = 4
w00t??
6/2(1+2)=9!
1st you do in brackets
(1+2)=3
then 2(1+2) = 2*3
6/2*3
6/2=3
3*3=9

damn maths! fuck you!

2(1+2) = 2x1 = 2 , + 2x2 = 4 , 4 + 2 = 6 --> 6:6 = 1 !
2(1+2) = 2 x 3 = 6 --> 6:6 = 1 !
you cannot multiply like that, you must consider 6/2 (=3) as single number (e.g. 6/2=9/3=12/4=3)
6/2(2+1)=3(2+1)=6+3 or 3*3=9
-
Well im just saying that you can also do it like this:
[2(1+2)] = 2x1 + 2x2 = 6 --> 6:6 = 1.
Because there is an X between 2 and (1+2) = 2 x (1+2)
Meh, i searched on the internet, and i now think its 9 too...
-
Why are you all this obsessed with maths.. really something is wrong with you guys.
-
9
-
u know nothing about algebra...
Then explain :D
-
I doesn't matter which one is correct, just stop entering calculations into the calculator in such an ambiguous way. :L

You should challenge yourself more through the day :L

this would be like 6/(2(1+2))

a = x
a + a = a + x
2a = a + x
2a - 2x = a + x - 2x
2(a - x) = a + x - 2x
2(a - x) = a - x
2 = 1
problems, mathematicians? :7
-
that does not say 2=1
it say a=x so when x = a we can swap one for another and don`t use them both
2(a-a)= 0 = a-a
so your unknown can be any number
-
a = x
a + a = a + x
2a = a + x
2a - 2x = a + x - 2x
2(a - x) = a + x - 2x
2(a - x) = a - x
2 = 1
problems, mathematicians? :7
division by 0 on last line
the answer to the first question is 9 because you do multiplication before division

2a - 2x = a + x - 2x

2(a - x) = a - x

? but if you do multiplicacion before division then it's 1 :o
or I didn't get it :L

BIDMAS Convention - Brackets, Index, Division, Multiplication, Addition, Subtraction in that order.
Therefore the answer is 9.
6/2*(1+2)
Brackets
6/2*3
Division
3*3
Multiplication
9

/ and * are on same level
6*4/2 = 24/2 = 12 = 6*2 =12 = 4/2*6 = 6/2*4 = 1/2*6*4
same with + and - are on same level
only () can change priority
() > ^ > * and / > + and - priority order where ^ is exp e.g. : 2^3 = 2*2*2 or 2^(1/2) = 2^0.5 = racine square(2) or 2^(-3 ) = 1/2^3 = 1/8 = 0.125 2^(1/3) = cubic racine(2) .....
here
answer is 9 ofc
and 2(a-x) = a-x
1st : a=x => a-x =0
2(a-x) = 2*0
2*0 = 0 : brillant ^^
0=0

this is an example, in what case u need to cross the multiplication or division
2a = 3(4/15)
2a = 3(4/15) ** then the 3 turns in 3/1
2a = 3/1 * 4/15 ** do the fractions multiplication
2a = 12/15 ** then the 2(a) or 2*a turns in a division ***multiplication to division = divison to multiplication
a = 12/15 / 2 ** then the 2 turns in 2/1
a = 12/15 / 2/1
a = 12/30 ** simplificated = 4/10
final result is a = 4/10
Checkout
2 (4/10) = 3 (4/15)
2/1 * 4/10 = 3/1 * 4/15
8/10 = 12/15 ** correct
0.8 = 0.8 ** correct
now lets go to your "simple operation"
6 / 2 (1+2) = x ** make ur parenthesis
6 / 2 (3) = x ** turn the parenthesis in a multiplication
6 / 2 * 3 = x ** do the multiplication
6 / 6 = x ** a number divided by itself is equal to one
1 = x ** correct

9 is correct
