Has anyone else seen the whole "6÷2(1+2)" problem on Facebook or elsewhere? I am completely blown away by how divided the responses are. I'm not great at math, but when both math logic and a graphing calculator give you an answer, you can't ignore it. Crazy.

I have not heard of that until now. It's kind of weird that people singled out that particular equation since it's the same deal for anything in that form, I guess they just used 6/2(3) because they can't bear to deal with decimals and needed something that had a whole number for an answer.

If people are really divided over it, that's pretty sad. In fact, it's sad that it's any kind of big deal, really. Anyone who thinks that it equals anything other than nine needs to go back to fifth grade and relearn the order of operations. 6/2(3) is the same as 6/2*3, which, going from left to right like normal, is 3*3 or 9. The two is not being multiplied before the division, or at all, the quotient of 6/2 is. Otherwise it would be 6/(2(3)), which is 1. But it isn't that.

You have chosen wisely!

Also, my cousin and 303,000 other people on FB said 1. This is of note because my cousin not only has her Master's degree in teaching, but she is also certified to be an administrator (school principal).

what I love about the 6/2(1+2) thing is you can see the results before you vote on it
so you not only have to be mistaken about how parenthetical multiplication works in terms of order of operations, but you have to assume the overwhelming majority of people that answered before you are wrong about it, and not bother to double check.

I'm also surprised at how many people didn't end up checking it with a graphing calculator. I saw some people at one site claiming that they are not accurate, but if you enter the damn problem correctly you'll get the correct answer. I don't know why I let this thing bother me so much.

[DiscoBallClock]

I too chose 9. Sad that people actually fret about this kinda thing.

[Topcatyo]

I remember in math class our teacher gave us an order of how you're supposed to do equations in a math problem.  There was some kinda pneumonic for it that I completely forget (thus spitting in the face of pneumonics), but it was something along the lines of you do exponents and parenthesis first (neither has priority over the other, but if you're doing more than one in an equation you go left to right), then you do multiplication and division (same thing about priority as the exponents and parenthesis), then the addition and subtraction.

So the order of operations would go like this:
1.) Exponents and Parenthesis, solving them going left to right
2.) Multiplication and Division, solving them going left to right
3.) Addition and Subtraction, solving them going left to right
Am I right in this or am I wrong?

If I'm right, 6/2(1+2) would be solved thus:

6/2(1+2)
6/2(3)
3(3)
9

So yeah, 9.

I'll be honest I came up with 1 the first time I did the problem in my head, but then I started writing out this post about the order of operations and taking that into account is when I finally got 9.

[DiscoBallClock]

I learned to do it in this order:

operations within parenthesis -> exponents -> multiplications or divisions -> sums or subtractions

But I don't remember anything about left to right or anything.

The going left to right was only ever applicable if you have the situation in the 6/2(1+2) equation, where you have 6/2(3).  In order to get 9 as the answer, you have to do the 6/2 first, since it's on the left, otherwise you do the 2x3 and get 6, then divide 6 by 6 and get the answer as 1.

I'ma look up order of operations though just to be sure I'm not going about it the wrong way.

[Topcatyo]

Yeah so Wikipedia says the order of operations is:

terms inside parenthesis
            exponents and roots
            multiplication and division
            addition and subtraction

So yeah, I was wrong about the parenthesis and exponents things. Although to be honest it makes sense that parenthesis would have priority over exponents so I dunno what I was thinking.

I aced my algebra final, son, you best step up your game.

How could you have done that if you don't even know that terms within parenthesis are solved before exponents and roots? >=)
