I have a masters degree in math and I teach it in college. I don't know the answer. It's for the simple reason that nobody uses the division symbol of that type past 8th grade.

Some of you need practice as badly as I did, I got a spark for engineering a few months back so I've been doing a lot of math lately. A really good place to practice is [link to www.khanacademy.org (secure)] and don't forget the math tricks [link to www.youtube.com]

Re: Math: 6÷2(1+2) = ?
My 4 year old can type 9 and call people morons. Back it up with something. Read THIS for example:

Distribute 2 into the parentheses. Why? because it is a factor of the original terms INSIDE them, and cannot be ripped apart. I will show you why:
6 = 4+2 = 2(2+1) = 2(3) The 2 is a common factor of 4 & 2.
No matter which way you view it, the value 6 MUST maintain its value. Just as you cannot take the 4 from (4+2) and divide it into a number with the "+ 2". I cannot take the 2 from 2(2+1) and divide it into another number without the (2+1).
You ARE allowed to distribute before division, or any other operator, since you are allowed to simplify any equation first. There are MANY references which state "Remove parentheses by distribution" Try Googling that as a search term.
6÷2(2+1) = 6÷(4+2) = 1
Now, some people have argued that you don't NEED to distribute the 2; you just add the 2+1, and end up with 2(3). Then they go on the say that this is the same as 2*(3). WRONG! You STILL have parentheses and STILL need to distribute that 2 inside them, for the reasons discussed about factoring above. Therefore you have this:
6÷2(3) and must distribute like this:
6÷2(3+0) = 6÷[2(3) + 2(0)] = 6÷6 = 1
These people who get 9 try and rip the 2 away from the parentheses by inserting a times symbol like this:
6÷2*(3), and then do the division of 6÷2 first. I explained the illegalities of doing this, since the 2 is a factor of the 2+1.
Lastly, 6÷2 is NOT (6/2), as in (6/2)(2+1). This is totally incorrect, since it lacks that parentheses in the original equation. Check any online or written text. Leading fractions as a coefficient ALWAYS have ( ) around them.
I hope this clears things up.
Regards.

Re: Math: 6÷2(1+2) = ?
If you think the equation should = 9 then it should look like this:

(6/2)(1+2)=

3*3 =9

but we have:

6/2(1+2)=

6/6 =1

because you do the sum in the bracket first.

So the answer is 1.

6/2(2+1) the sign you use for division in this problem doesnt matter.

seems all agree we must get rid of the ()

so we do whats in the () first by adding 2+1 to get 3

so 6/2(3)

we still have those pesky () so we must get rid of them first

so we now multiply 2 by the 3 in ()

we have now gotten rid of the () and are left with the simple equation

6/6

however I wish to write that problem I will always get 1

Sorry but you divided 6 by 2 before getting rid of the () thus violating the order of operations.

Re: Math: 6÷2(1+2) = ?
The 2 is not inside of the parenthesis therefore need not be distributed. In order to mandate the distribution of 2, the problem would have to read as 6÷(2(1+2)). Since it is not, PEMDAS works it out just fine. 6÷2(1+2) becomes 6÷2(3), which is the same as 6÷2*3. Simple order of operations.
