Once and for all i want to know the real answe to this equation...

is it 1 or 9?

Hope somebody here knows their maths

6/2 = 3
2+1=3

3x3 = 9

I don't see how you would get "1" from that

Do the parenthesis first, multiply by 2 and divide by six...the answer is 1. That's elementary.

6÷2(1+2)=?

Order of operations: BEDMAS

Brackets
Exponents
Division
Multiplication
Addition
Subtraction

1+2=3
2x3=6
6/6=1

Well... what's the question? My g/f is pretty good at maths..

Edit to add: nevermind. I will run it past her though... I have an old maths lecturer that I can pass this on to aswell...

well that would make sense of it then...

I'm guessing this equation is designed to be confusing?

Really!!!!???

6/2(2+1)

6/2=3 x 2+1=3

3 x 3 = 9

The answer is 9, im not even that smart

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.

6÷2(1+2)

6/2 = 3
3(3) = 9

simple enough.

That's not entirely accurate:

Please Excuse My Dear Aunt Sally

Please -- Parenthesis
Excuse -- Exponents
My ------- Multiplication
Dear ----- Division
Aunt ----- Addition
Sally ----- Subtraction

already half of you put 9 and half of you put 1, so which is it, 1 or 9?

if division is before multiplication in operation order wouldn't it be

1+2=3
6/2=3
3x3=9?

Believe me, it's 9!

6÷2(1+2)=?,

BEDMAS...

Brackets (1+2) = 3
Division 6/2 =3
Multiplication 3 x 3 = 9

Had you said 6/(2(1+2)) = 1 i would have agreed... but you did not. The equasion is 6/2(1+2) hence 9.

BTW, in BEDMAS, Division and Multiplication are done at the same time... meaning the one furthest to the left gets done first. Similar with Addition and Subtraction.

omg guys...
6/2(2+1)
Parenthesis
Exponentials
Multiplication
Division
Addition
Subtraction...

you do not DIVIDE 6/2 first..
U ADD WHATS IN PARENTHESIS, THEN MULTIPLY BY 2...

This is 3rd grade my friends.. what schools are you going to??

6 divided by [ 2 * (2+1) = 6 ] TOTALS TO 6 divided 6 which in turn equal 1...

thanks

It's 9 because to get the answer one you have to do an order of operations error.

In this case to get 1 you would do:

6÷2(1+2)

6/2(3)
6/6 = 1.

What they don't realize is that 2 is not part of brackets and they treat it as if it does.

The real solution is in my above post.

So simple maths isnt allways simple


I'm glad i put 1, the more you say 1 is correct the more happy i am.
