Replace the division sign with the / sign. It is the same operator, just a different form that allows users that don't have direct access to a division sign (ie: nearly everyone with a keyboard) to perform multiplication. The same reason that the multiplication sign is represented by * on a computer. _________________

Oh... I did that already... that's not what caused the error... it's the lack of an instruction surrounding the (3) that created the error. _________________

Excel probably doesn't account for multiplication via parenthesis then. Write it like this:
6/2*3 _________________

Well, I didn't include the ()'s because his version of excel seems to hate them. But you're right on the = sign. To this day, and I've been using Excel for... more years than I want to count, I still, always, forget to put the = sign in first. Then I go back. _________________

Not a math wiz, but I know the answers 9. I still have the ruler marks from where my algebra teacher smacked me in school. _________________ Malorn ‎(12:14 AM):

lol I was more pointing out that the paranthesis work, so long as you put a * before it.
And...

The answer is: 42

As far as I know, and like others have said, you do whatever's in parentheses first. 1+2 = 3, and you immediately multiply it by 2 since it's been condensed. Expanded it would be (1+2)+(1+2) which equals 6 either way. And 6 divided by 6 is 1.
Now, I could be wrong, but this is how it was taught to me. PEMDAS... please eat my daughter's atrocious salad. Or whatever. Parantheses, e... I honestly forget what the e stands for. Exponents? I just woke up. Then multiply, divide, add, subtract. You do everything in that order.
I can see how it could also be 9, but you get that number by solving the problem incorrectly (I'm pretty sure anyway). It seems like a really simple problem to me, but perhaps because it's so simple, it's confusing? Hmm. But I'm almost positive the answer is 1. That is, if my teachers weren't lying to me throughout middle school/high school. And my one awful college math class.

You would do it that way, Ekoth, if it were written like this:
6/[2(1+2)]
You are right, though. Parenthesis first. Which means you end up with 6/2(3). Then, by rule of PEMDAS, you must go from left to right with multiplication/division. That gives you 9.
The reason you do not multiply 2 to (1+2) first, is because the way it is written indicates the following:
6 (1+2)
2
Which says six over two, then multiply the product by the sum of one and two.
The way you are solving the problem would look like this:
6____
2(1+2)
Which is six over the product of two and the sum of one and two. _________________
