Why did the vector cross the road? It wanted to be normal. #82 20070209 15:17:42
Re: Brain TeasersAbsolutely right, mathsyperson! Well done!!! Character is who you are when no one is looking. #83 20070330 22:01:07

Re: Brain TeasersMaybe I just missed it, but I never did see an answer to #5. #86 20070424 04:55:34

Re: Brain TeasersI would guess that question 5 wants you to find two distinct natural numbers, as allowing them to be equal or 0 would trivialise the question. Why did the vector cross the road? It wanted to be normal. #88 20070424 18:55:00
Re: Brain Teasers4. The total I got is 7. Eeyore, you must have made some calculation errors. I shall be on leave until I say so... #89 20070428 02:56:46
Re: Brain Teasersgood job Landof, I don't know what I was thinkin, if she started with 3 and did all the stuff the problem says she did, she would still have half an orange left. #90 20070531 18:00:30
Re: Brain Teasers49. How many squares are there in all in a chess board? (Treating 2squares by 2 squares as a square etc.) Character is who you are when no one is looking. #92 20070531 19:23:45
Re: Brain TeasersUsing the same method as above, you should also be able to prove that the total number of rectangles on a chessboard (counting squares as rectangles) is . #93 20070531 23:25:19
Re: Brain TeasersOutstanding, Identity and Jane Fairfax, for that simple and elegant proof!!! Character is who you are when no one is looking. #94 20071110 01:35:27
Re: Brain Teasers50A. A farmer has a piece of land of the shape given in the uploaded image (1001A). He has four sons. He desires divinding the land amongst his four sons. The four sons aren't very smart, they insist on the pieces of land being of the same area as the original land and also the same shape.

Trillian: Five to one against and falling. Four to one against and falling… Three to one, two, one. Probability factor of one to one. We have normality. I repeat, we have normality. Anything you still can’t cope with is therefore your own problem. #100 20071213 01:26:15
Re: Brain TeasersExcellent, NullRoot!!! Your answer is perfectly right!!! Character is who you are when no one is looking.
