## Math: 6÷2(1+2) = ? | |

BadHairDayUser ID: 30857551 Australia 01/14/2013 10:33 AM Report Abusive Post Report Copyright Violation | I give up. I could get a Harvard Professor or even Steven Hawkings to explain this and you idiots would still thin Quoting: k it is 1 Some people are just to o stupid. Obviously it is pointless trying to explain it to you. If you can't work out that this is 6 ÷ 0.666666666666 and not 6 / 6 then your better off believing the 911 and Sandy Hook story than questioning it because there is no telling what you would do when you found out the real answer.Anonymous Coward 30235756 Your logic, and spelling is aweful. Why would you bring 911 and Sandy Hook into an argument about maths? And why are you so upset about an equation? Chill dude... It's all about the 'vibe' |

I was never taught any mnemonic. I was taught order of operations, factoring, algebra, calculus, etc... How about these refs then?: "We use the distributive property to help us find a way around the order of operations while still being sure that we keep the value of the expression."

Anonymous Coward User ID: 20566260 United States 01/14/2013 11:48 AM Report Abusive Post Report Copyright Violation | You almost had it. After parenth you are supposed to move left to right. You solved 2*3 first, but instead you should have done 6/2 first. Then you would have been left with 3(3) which is 9. J&V no! you dont just leave (3) if youre left with (3) or any other number you are supposed to finish it! and then do left to right DPS There is nothing left to do with (3) You cant just make something up. |

cantlive4everUser ID: 29341887 United States 01/14/2013 11:55 AM Report Abusive Post Report Copyright Violation | The correct answer is 9. Multiplication and division take precedent over addition and subtraction. HOWEVER, multiplication and division are of equal precedence, as are addition and subtraction. To show the work it would be: Parenthesis first (1+2)=3 So now we have 6 divided by 2 times 3 Since division and multiplication are of equal precidence work left to right: 6 divided by 2=3 Now we are left with 3*3=9. The confusion seems to be with how we are taught at a very young age. We are all taught things like PEMDAS, BEDMAS or BIDMAS and we forget that multiplication and division are equal as are subtraction and addition. Remember, I made these predictions before I correlated them to the Mayan long count or studied the prophecies of the cleansing. |

(3) is equivalent to 3 is it not? So you can eliminate the parentheses, and change (3) to 3. Anonymous Coward 31519086 Exactly!!! So 3(3) = 9! |

Let's see how your logic holds up against some basic mathematics. Quoting: 6÷2(1+2) = ? I'll give two hints. This is NOT a trick question, and there is only 1 correct answer. All tools used for computation are fair game. (Yes, I saw this somewhere else and decided to post it here.) Best of luck to all you geniuses .
