    Oh I'm not trolling... Just trying to figure out how you guys are separating it out.

    Using that logic, that means 6

    From a previous wiki reference -



    Similarly, care must be exercised when using the slash ('/') symbol. The string of characters "1/2x" is interpreted by the above conventions as (1/2)x. The contrary interpretation should be written explicitly as 1/(2x).


    Substitute (1+2) for x and it's case closed.

    The division sign was covered by the mathematician.

    You were taught that 3x is the same as 3*x, focus on that.

    That one I can follow.

    6/2(x+y) being equal to 3(x+y) I have trouble following.

    substituting (1+2) for x in that example is still not the same, as you only have the multiplier.

    So you can follow my logic, I was taught 6/2(x+y)
    is
    6
    ---
    2(x+y)

    which is same as

    6
    ---
    2x +2y

    Sounds like something to send to school with my son, and see what answer his algebra IV professor sends back :)


    EDIT: never mind - I see your reference . almost 5am here.
    1/2x = 1/2(x), 6/2x = 6/2(x).

    Still curious as to what his prof will say :)

    Whoo Hoo!!! Another objectivist. EarlyMon solves the equation A=A. Nice to find a kindred spirit.

    That's the part that's incorrect.


    6/2(x+y)

    is

    6
    --- (x+y)
    2

    See the difference? You can't put just the 2 in the parenthesis, the way you're doing it, you're supposed to multiply the entire "six halves" against x and y.

    The 6/2 part doesnt need a parenthesis to go before the 2 * (3) part since it's equal in order of operations and leftmost.

    Oh, don't worry guys - it was a MAJOR facepalm moment when the light turned on :D

    His example, fyi, if you were to ask me what 1/2(1+2) was, I could literally read it out as "one half times one plus two". so, 6/2, 1/2, makes no difference. Call it "six halves times one plus two" and the result is 9.

    Guess that's why it's a math problem. I assume it's the 6/2 throwing folks off, I dunno. I think if you were to ask what 1/2(1+2), most people would probably get it right :)

    And to answer n0ct3m, yes, it's settled, and the answer is 9.

    And, sadly, the Atrix bootloader is still locked :)

    Oh, and I'd like to apologize to my teachers, because there is NO WAY they taught me that 6/2(1+2) = 1 :eek:

    I still maintain the answer is 42.

    I maintain that this thread is full of nerds. I don't think that puts me in a very good position now....

    I did that shit in my head....

    The answer to the problem depends on how it's written and in this case...
    6/2(1+2)
    6 / 2 * 3
    3*3
    9

    You always do math left to right, like reading a book, or this post. Always solve for whats in parentheses first. Then solve ops like square roots & powers. Then solve muliplication & division, left to right. Then addition & subtraction, left to right.

    It's not phrased "6 / 2 + (1 + 2)" so how you get anything but "9" is beyond me.
