I've learned more about math in this thread than my Algebra, Geometry, Algebra II and Pre-Calculus classes combined.
That was a lie.
I never took Algebra. |

It's 120!/(2!3!) with 5*Sum_{n=0}^{inf} 2^{-i}, pretty early huh? |

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... |

Technically, this clock isn't only for geeks. Yes, they are the ones who'd get a kick out of it, but you would have to be a complete idiot not to know which numbers the equations translate to. |

Are you people *still* debating the 0.999... = 1 thing? |

2 is an infinite sum.
We got them all. Very cool clock. I would pay money for this... |

@ trashcan 7
2 is just summation notation for the infinite geometric sum of 1/2 |

If you're still wondering what they are, look up in the more comments: page 1 should still have my posts where they're all explained in detail (it's 3 posts). |

Lionhart explaining the clock:
"Here:
1. Legendre's Constant
2. ???
3. Unicode HTML
4. Modular arithmetic
5. Golden Mean
6. Factorial 3
7. 6.99999...
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." |

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.

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

I'm in Alg. II and I get 10...?
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) |

@Fatninja01, 3!, does not equal 6! at all.
3!=3*2*1=6
6!=6*5*so on and so forth. |

"Ikeray: this proof works better.
X=0.99...
10X=9.99...
10X-X=9
9X=9
X=1=0.99..."
problem with this is that .99 x 10 is 9.90, not 9.99 |

@tozhan
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. |

Ikeray: this proof works better.
X=0.99...
10X=9.99...
10X-X=9
9X=9
X=1=0.99... |

I have no idea what these mean, but I can still figure out what time it is. Does that make me a super genius? |

mluther, the 1/3, 2/3, 3/3 isn't as good an explanation as .111...=1/9, .888...=8/9, .999...=9/9=1 |

they should have used eulers identity for 1... that won is way cooler. |
