I'll admit I misused pemdas in my original post, neither Multiplication nor Division get preference, you read left to right.

In the form of the original question:

6÷2(1+2)
6÷2*3
3*3
=9

When wrote as:

6/2(1+2)

You can interpret it two ways:

6/2(1+2)
6/2*3 (Again, left to right, / = ÷)
3*3
=9

OR

6(FRACTION)2(1+2)
6/(2*3)
6/6
=1

THE CONCLUSION

The question is poorly wrote and would never appear on an exam like that.
The question would VERY CLEARLY be:
6/2(1+2) or 6/(2(1+2))

The last two equations you wrote, "6/2(1+2) or 6/(2(1+2))", are the same. They both = 1.

whoever thinks its 1 fails at math, u do the brackets first then since division and multiplication is of same importance you read it from left to right like a book so comes to (6 / 2) * (1 + 2) =9

A fraction is the top number divided by the bottom number. How is a division sign not a fraction of the two numbers?

It is a fraction, but you're dividing the wrong numbers. Everyone knows that for this equation:

1+4
-----
1+9

You get 1/2. You solve for the top, then solve for the bottom, then divide the top by the bottom. But, this equation is actually:

(1+4)
------
(1+9)

Both the equation in the numerator and the equation in the denominator are separate equations. You and a few others are interpreting 6÷2(1+2) as:

6
------
2(1+2)

But in reality, it's not. The ÷ is not a fraction bar. The ÷ is a division symbol, and according to the order of operations, you solve as such:

6÷2 = 3
1+2 = 3
3*3 = 9

another guy who added a parenthese which isn't there to begin with

by adding smth that doesnt exist to begin with you change the whole outcome

get a fucking clue

ok now im rly off to bed, but i'll definitely read when i get back tomorrow for more lulz

okay lets break it down

BEDMAS

Brackets first

(1+2) = 3

Since this was bracketed, it need to be x with the number to the left of the bracket....

2(3) = 6

6/6 = what?

Wow Jsp. Its sad that majority of you think 9 is right. If you've had your hand on 1 all along, Congrats guys, We are a dieing breed.

yup yup. hilarious thread

I added parentheses to show you where you separate the equation. If you had passed 4th grade math, you would have figured this out by now.
