Another math problem...I wonder how long this one will take.

Maybe if you turn π into 9, then...never mind.

sorry for being so picky but i don't think you can use a exercise ball to crush a ping pong ball without picking it up
I don't know, exercise balls are pretty heavy. Why don't we try it?

I see.

I've got no clue. Still thinking.

Did we save Bill, or is he dead as well?

Joining all the faces everyone has said I can find around 22
I have an odd feeling that there aren't supposed to be that many.

I don't get it. What's it supposed to do, if anything?

It's strange how often these types of puzzles seem so impossible when you don't know the answer and so easy when you do. Good puzzle!

in this riddle, it shouldn't
Just checking.

Nice work everybody. That was quick. It's my first puzzle I've posted here so I hope it wasn't too easy.

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 pingpong (table tennis) ball and the soccer ball turned into a massive hard exercise ball. The exercise ball rolled around, trying to crush the pingpong ball. Without leaving the floor, is there any way the pingpong ball can prevent being crushed?

Can => also be read as ≥?

Your answer of noon and 400 days is correct
Assuming you wear your Santa's hat on 12/25/2012, Christmas day, then your date is in error!
is the fact that 2012 is a leap year, hence 366 days long.
Pity...it would have been an interesting coincidence.

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...

I got that the number of numbers that their sum of digits is 23 is:
10277480826812889625905461378557875572691517481461831953754147520719499605119655242154450033684486429472192740396263
4451048727505353916055952983108252807002074097238922492488792290093878660391122987835044950137411384570184547711214397672
43201237672648884843921745555
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.

Interesting... I'll have to try it on my friends.

I like these ones. Sometimes it's better when the equations are more complicated because it hides the division by zero. Good puzzle!

Is this actually still being discussed? It was started at the end of 2007!

Whoops, just saw jaisha's Wikipedia link.

Design a track through the lands so that you cross each of the seven connections labeled, only once. All connections have to be completely traversed exactly once. The track must be unidirectional, i.e. you cannot doubleback and move the way you came. (This one seems impossible)
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.

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.

What do you mean by π => 9? Is it part of the code?

What? Why did my post just break? I suppose it doesn't matter. But I wonder what "<blank>" means.
