The one she saw on Facebook was 6÷2(1+2). No potential fraction, less confusing. No real excuse for people to be answering 1.
My cousin got in an argument with some girl about this yesterday. I said he was right and she implied I was either a liar or stupid (I said I was a math teacher and she said "I can claim math teacher" and "I've had a lot of stupid teachers"), and then called us rude when she figured out she really was wrong. And then she deleted all of her comments before I had a chance to screencap them for Failbook. Damn.
Anyway, it's 9.
To anyone that's unclear, multiplication/division and addition/subtraction are inverse operations, and therefore the order of them is interchangable. PEDMSA is just as valid as PEMDAS.
So you do what's in the parenthesis, which simplifies the problem to 6÷2(3). The 2(3) is multiplication. It's expressed with a parenthesis, but it is still just multiplication.
That said, you do the remainder of the problem left-to-right: six, divided by two, and then times three.
This is fifth grade math. Maybe fourth.Originally Posted by Goldenboko
