    [Mathematics] Therefore 2 = 1

    In honor of the absolutely atrocious mathematics of World of Warcraft players as recently showcased in this thread here http://www.mmo-champion.com/threads/899641-6÷2(1-2), I decided to cause some more mischief and see if people can figure out how I proved 2 is equal to 1 (and where my intentional error is)

    Given: a = b:

    a^2 = ab
    a^2 - b^2 = ab - b^2
    (a + b)(a - b) = b(a - b)
    (a + b) = b
    a + a = a
    2a = a
    2 = 1

    P.S. the ^ is to indicate power its raised to. 4^2 = 16 (4 squared = 16).

    (a - b) = 0, your step 4 is a divide by 0.

    Concur with Waniou, you're dividing by zero.

    At least you didn't use the piss poor representation of this same problem where they use .99999.... and .9999...999

    Damnit, Waniou was first
    Yeah, as Waniou said, you're not allowed to divide by zero. (I heard that there is a "number range" where that is possible (like complex numbers to real numbers (squareroot from -1)), but it is too abstract to imagine what it's like... not sure about that tho)

    whats with all the mathematics trolls these days?
    and yes, you are dividing by zero.
    the correct solution would be
    a^2 = ab
    -> a=b

    famous one, IIRC I saw one during my engineer studies that "proved" 1 = 3, by using sqrt(-1) = i, I'm not sure how it went, should have it somewhere in my old books

    The i problem is where 1 = 2 using complex numbers, the fallacy usually being when they sqrt(-1/1) = sqrt(1/-1) and simplify to sqrt(-1)/sqrt(1) = sqrt(1)/sqrt(-1) except the rule they're using only applies to positive numbers, and no such rule for negatives exists.

    The answer is 9!

    Technicly you can divide by zero, the answer escapes our universe -> black hole.

    Let x = 0.99999...
    Then 10x = 9.999999...
    Subtract the first line from the second line.
    9x = 9
    x = 1
    0.999=1

    Too easy, operators do not hold their properties on numbers that have not been defined.

    well you can get that one easier.

    1/3=0.33333... (period 3) so technically it never ends.
    (1/3)*3=0.33333....*3
    1=0.99999...
