1. Nice work everybody. That was quick. It's my first puzzle I've posted here so I hope it wasn't too easy.
2. I read about this in a Russian puzzle book and I don't think it's been posted before. A soccer goalie had just lost an important match, and when he went to sleep that night he had a strange dream. He dreamt that he was kicking a soccer ball against a wall, and as he did so, the soccer ball got bigger and bigger, and the goalie got smaller and smaller. Suddenly, the goalie turned into a ping-pong (table tennis) ball and the soccer ball turned into a massive hard exercise ball. The exercise ball rolled around, trying to crush the ping-pong ball. Without leaving the floor, is there any way the ping-pong ball can prevent being crushed?
3. Can => also be read as ≥?
4. Pity...it would have been an interesting coincidence.
5. By the way, is that number actually divisible by 23? I suppose that there's a 1 in 23 chance that any number is divisible by 23, but I wonder if there's some mathematical connection...
6. Why aren't there an infinite number of numbers whose digits sum to 23? For example, if we take 6 as the number the digits sum to, the number 123 has digit sum of 6 but so do 1023, 1230, 1203, 10023, and anything else obtained by adding 0's.
7. ## Impossible Paper

Interesting... I'll have to try it on my friends.
8. ## 4=3... Where did I go wrong?

I like these ones. Sometimes it's better when the equations are more complicated because it hides the division by zero. Good puzzle!
9. ## Hats on a death row!! One of my favorites puzzles!

Is this actually still being discussed? It was started at the end of 2007!
10. Whoops, just saw jaisha's Wikipedia link.
11. Assuming the labeled connections are the only ones, adding another bridge is the only way to solve it. This was first posed by the mathematician Euler in regard to the bridges of the Russian city of Königsberg.
12. ## 2=1 How can this be true? read to find out

This reminds me a bit of when we did systems of equations/inequalities in math class and we got nonsense like 7=5 or 0>11 when there was no solution.
13. What do you mean by π => 9? Is it part of the code?
