    The Long Lost Debate...

    Forums used to be all over this thing...

    SO .9 repeated, that is, .99999.. for infinity, (or .9~) is exactly equal to 1

    Which means that every single decimal value has two decimal representations of that value.

    Many do not believe this, even after seeing this proof:

    1/3 = .3~

    1/3 * 3 = 1 and .3~ * 3 equals .9~

    Therefore, 1 = .9~

    What are your thoughts?

    No, .9~ is not 1. It is an irrational number. On a number line, .9~ would have its own spot, it would not lie on 1. If you multiply a number by .9~ you will not get the same answer as when you multiply a number 1. .9~ is approximately equal to one but they are 2 completely different numbers.

    "Religions are, by definition, metaphors, after all: God is a dream, a hope, a woman, an ironist, a father, a city, a house of many rooms, a watchmaker who left his prize chronometer in the desert, someone who loves you—even, perhaps, against all evidence, a celestial being whose only interest is to make sure your football team, army, business, or marriage thrives, prospers, and triumphs over all opposition. Religions are places to stand and look and act, vantage points from which to view the world. So none of this is happening. Such things could not occur. Never a word of it is literally true.”

    I'm not saying you are wrong, but I think you would find this article interesting:

    I did, since i'm not well versed in this topic, and I checked out a video as well.


    Personally i believe all these proofs are in fact invalid.

    Also, the same bright female that made that video made another video showing why the reasons she posted are wrong.

    I'm watching the video now and will explain why the disproofs are wrong.

    1. In the first example she had the following equation:

    .2~ = x
    2.2~ = 2x <--- Here is a problem. .2~ * 2 = .4~ OR if adding 2 then it should be x + 2
    2.2~ - x = x
    2=1

    2.

    There are different levels of infinity, all within the same infinity. Example: you own a hotel with an infinite amount of rooms. Then, and infinite amount of people show up. You can provide everyone with a room. However, another infinite amount of people show up, but the hotel is full. To solve the problem, you tell everyone in the hotel to move to an even room. There is then an infinite amount of rooms available, and 2 groups of infinite people can fit in one group of infinite rooms. The same works for .9~

    Also, .0~ with a one on the end (or any value at all) is infinitesimal.. or in other words 0.

    3.

    Wow it's an april fool's joke.. did you just set me up lol

    Haha yes mate, .9~ does equal one. I mean hey I take the mathematicians word for it.

    ​I used to fight it, but .99999999 technically IS one, even if it seems mathematically contradictory.
    I am the seer in the dark,
    the vagabond of yore,
    valediction.
    I am the sum of all your parts,
    and proprietor of all.
    A miasma,
    the conclusion,
    blackmonger of Inlé,
    valediction.
    Synapses fray,
    my form now vivid,
    as torpor sets and blood grows tepid.
    With every ounce of flesh now offered,
    I hold your corpse within my coffers.
    Knitted cells now split asunder,
    stand alongside me brother.
    Take your place amongst my Owsla,
    we march at dawn now and forever.

    Kind of a pointless argument as it's use in math isn't that great.

    :/
