    Can someone explain 3 and 11?

    I took 21 hours of math, and I haven`t a clue on 3. 11 is just A hexadecimal number. 0x is the prefix that says what follows is a hexadecimal number, and 0B is 11 (08, 09, 0A, 0B, 0C, 0D, 0E, 0F, 10, 11...)

    11 is being being expressed in hexadecimal, so that`s just a change of base.

    I don`t even recognise the symbols used in 3.

    Found it thanks to Google, number 2 is a reference to a joke about infinite parabolic curves which become closer to the integer with each iteration without every equalling it.

    The joke is:
    An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third, a quarter of a beer. The fourth, one-eighth of a beer. The fifth, one-sixteenth of a beer. The sixth...

    The bartender says "You`re all idiots", and pours two beers.

    No it doesn`t. It means that you are infinitely coming closer to 2 by an infinitely smaller number.

    seriously, all you people who think 0.999 repeating is NOT 1 need to go to class and listen -_-

    There are various ways to prove it, but here`s a simpler way too look at it. 1/9 is 0.1repeating. x/9 is 0.xrepeating. So what is 9/9? 0.9repeating which equals 1.

    I believe that what trashcan7 is trying to say is that the number .999999 repeating to infinity becomes a number so very close to the integer 1 that it actually can be evaluated as the number 1, with little deviation. It`s called the limit of a number

    Asymptotes. A number can get as close to x without ever reaching it. theorectically, you can keep putting 9`s after the decimal and it should never tough the asymptote. Of course this is just my way of thinking.

    @ jazzoon. 1/9 is 0.1repeating. x/9 is 0.xrepeating. So what is 9/9? 0.9repeating which equals 1.

    So x=11 11/9 Does not equal 0.11repeating.

    #7
    6.999_ = 6 + 0.999_


    0.999_ = 0.9+0.09+0.009+...
    a=0.9 r=1/10
    With infinite terms:
    0.9/(1-1/10)=0.9/0.9 = 1
    So 6.999_ does equal 7
    Still, believe what you want and call others idiots for disagreeing. Commence insults.

    Correct - I agree that for a "math geek clock" that is MATHEMETICALLY correct. However, since other number systems are present here, such as the human system called "time", if it was .0000000000001 seconds before 7 o`clock and someone asked you the time, you`d round it and say "7 o clock". Obviously, we`d all be a lot happier if they had used `approximately equal to` on the clock, but you`re right, a recurring decimal never actually equals the integer.

    I read the joke as a contrast between everyday practicality and abstract maths.

    The bartender`s action addresses the issue in a fast and effective way - the second pint will be enough to meet the orders of the mathematicians because between them they will never quite drink the whole pint.

    6 repetend 9 does not equal 7. EVER.
    You just had to include that hearty "EVER" at the end didn`t you? I suppose if you didn`t there might just be times when it does equal 7, as if the terms somehow felt the need to be equal.

    A recurring decimal does = 1

    Here is an example: 1/3 = .3333...

    so 3/3 = .9999...but also 1

    It`s the same.

    DAMN but you`re good at that math thingy!

    Actually, look closely enough and you`ll see that 11/9 IS a bunch of 11 repeatings. Only each one occupies 2 decimal places. 1.1, 0.11, 0.011, 0.0011... Add them all up and you get 1.22repeating. But anyway, you`re missing the point. This is just a simplified explanation. If you`re interested in the more lengthy ones, you could probably just look up the proof on the internet. I know its in my notes somewhere here but i`m much too lazy to look for it now haha.

    K here they are, explained in detail (each)

    1. Legendre`s constant (historical since B = 1). I would`ve used something more fun for 1 like -e^{i Pi}, but oh well

    2. Imagine the result of that sum is "S", so:
    S = 1 + 1/2 + 1/4 + ...
    2S = 2 + 1 + 1/2 + 1/4 + ...
    Now, 2S - S = S = 2
    It`s not approximate, since the sum is infinite, this is an exact result.

    3. Unicode HTML in hex for numbers, except I have no idea where the i comes from, 3 can be easily represented as &#x33

    4. Using the definition of inverse modulo, bb^{-1} = 1 mod 7
    1 mod 7 = 1,
    It`s the numerator in 1/7.
    So let`s find the number that has the same numerator when divided by seven and multiplied by (2^{-1})^{-1} = 2
    8/7 = 1 + 1/7, so bb^{-1} = 8, and since b^{-1} = 2, that makes b = 4. In this notation, b^{-1} is NOT 1/b.

    5. The golden ratio is (1 + sqrt(5))/2 = f, so 2f - 1 = sqrt(5) and its square is 5

    6. 3! = 1*2*3 = 6

    7. (The controversial one), if 6.999... wasn`t infinite, then you`d be right, it wouldn`t be 7. But in a space that admits infinities, you can`t make a distinction between
    6.999... < 7 < 7.0000...
    because there`s no concept of sequence for infinities, same as with 2., this is also an exact result.
    (See Galileo`s paradox to see why you can`t make sequences with infinities, if you count every number in an infinite sequence, and you count the number of squares in the same sequence you find that they both have the same number of elements, which is wrong because every square is in the same sequence. 1,2,3, ... inf, is gonna have inf numbers. but 1, 4, 9, ... is also going to have inf numbers, but the second sequence "should" be smaller since every number of it is contained in the first one.)

    8. Binary, from right to left: 0*(2^0) + 0*(2^1) + 0*(2^2) + 1*(2^3) = 8

    9. Base 4: 1*(4^0) + 2*(4^2) = 9
    (why so many bases? so far it`s been 2 hex,

    9. Base 4: 1*(4^0) + 2*(4^2) = 9
    (why so many bases? so far it`s been 2 hex, one binary and one 4 ...) Also, I always write them backwards because I like 0,1,2,...,n instead of n,...,3,2,1,0

    10. (5 2) = 5!/(3!2!) = 120/(6*2) = 10

    11. Base 16, where A = 10, B=11, ... and the UNIX prefix 0x is used:
    0x0B = 0B(Hex) = 11*(16^0) + 0*(16^1) = 11

    12. 12*12*12 = 1728, so it`s cubic root is 12.
    It would`ve been more fun to write 1729 + i^2, if only because 1729 is a much more interesting and convoluted number.

    For those of you still caught in the days of the ancient Greeks and do not believe in the convergence of a repeating number or series I submit to you two proofs:
    10(.99...)=10/9=9.99...
    (10-1)(.99...)=9/9=9.99...-.99...=9
    9(.99...)=9
    therefore .99...=1
    Or if you do not believe that we can use physical evidence with Xeno`s paradox with an infinite series which approaches 1 slower then .9 repeating (ie if it converges so must .99...; before one travels 1 foot they must first travel .5 feet then .25 feet and so on; if this never adds to one then then all movement is impossible. The B is legrende`s constant which is based on a series using the prime counting function, 11 and 9 are just different bases and 10 is not a matrix function but 5 choose 2.

    I don`t really think that proof is valid. You need to show why 10X-X=9. The person who doesn`t understand that .999... = 1 won`t really understand that the decimal portion of 10X equals the decimal portion of X.

    problem with this is that .99 x 10 is 9.90, not 9.99

    And an easier way to get it wouldn`t be 120/6*2
    Just do 5*4/2*1 (since you can cancel the 3*2*1)

    yanging... even those who disagree that .999...=1 would disagree with your statement.

    Do you know what .99... means? It means that the 9 is repeating infinitely. You can`t say .99... *10= 9.90; that`s completely ignoring what the proof is telling you.

    Anyways, I can`t believe you don`t believe that .99... is not 1. You can`t look at it differently; that`s the beauty of math: it`s straight-up true or not.

    Wiki

    If you are still arguing this, try taking a basic calculus course and then come talk.

    8. Binary (1x2^3 + 0x2^2 + 0x2^1 + 0x2^0)
    9. Base-4 (like Binary is Base 2 and Hex is Base 16, this is Base 4 numbering)
    10. Binomial Coefficient
    11. Hexadecimal
    12. Cube root=inverse of 12^3

    No idea on number 2."

    Frig me gently, I had no idea we had so many resident math nerds here at IAB. And many unfamiliar users who stay quiet through the standard-fare religious, political and ideological flame wars, but who come out gunning at the first hint of a bit of math.

    Don`t get me wrong, I`m not poking fun, I love this.

    IAB is a complex community, with many undercurrents and subcultures...
