1) 1+7
2) 4*3
3) 12-9
4) 14/7
5) How many two dimensional surfaces does a seven dimensional (hyper) cube have? Justify your answer.

1. 8
2. 12
3. 3
3. 2
5. 672. (E sub m,n = 2 to the n-m * (n! / m!(n-m)!) where n equals cube dimensions and m equals surface dimensions.)Last edit: 2008-04-19 12:29:25 |

Is that what you get when the take the matrix:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1
1 7 21 35 35 23 7 1
and square it?Last edit: 2008-04-19 12:34:23 |

I just found a formula to solve the problem, the actual math/reasoning involved is way above my head, sorry. 
Edit: And I don't even remember how to do the simplest of calculations using matrices.Last edit: 2008-04-19 12:35:09 |

Tomorrow when I have time I'll run through the calculations for my method to check if you are correct (unless someone else comes here and gives a convincing response) |

| if you fix 5 coordinates, the remaining 2 coordinates determine a unit square... thus 632 Last edit: 2008-04-19 12:37:20 |

It's just satire but I didn't want to make a COMPLETELY insubstantial post so I added a random math procedure I vaguely understand (with no other exigency for posting it).
azndsh I think you need to explain that..Last edit: 2008-04-19 12:38:10 |

say your hypercube has coordinates either 0 or 1 in 7 dimensional space.
Thus, one of these squares would be the following four points
(0, 0, 0, 0, 0, 0 ,0)
(1, 0, 0, 0, 0, 0, 0)
(0, 1, 0, 0, 0, 0, 0)
(1, 1, 0, 0, 0, 0, 0)
Notice that only the first 2 coordinates are different. Its easy to see that is true for any unit square. I could describe this square as
(x, x, 0, 0, 0, 0, 0)
Thus 5 coordinates are fixed, while the remaining 2 describe the square.
There are (7 choose 5) * 2^5 ways to fix 5 coordinates
The other formula corresponds to the general case.Last edit: 2008-04-19 12:46:26 |

| According to my method I get 21x1 + 35x3 + 35x6 + 21x10 + 7x15 + 1x21 = 672. I think lemonwalrus' method was correct azndsh |

Azndsh's method, as far as I can tell, supports my method, but simply shows that my method is only applicable under certain conditions, where his is more universal. Then again I might be trying to understand things that I simply cannot.
Edit: (7 choose 5) * 2^5 = 672, right?Last edit: 2008-04-19 12:57:33 |

yes, my method is exactly how to arrive at your formula
you can extend the argument to arbitrary (m,n) |

| So... is it 632 or 672... |
