Don't forget that you have to add up the price for all the individual nails. So your calculation is correct for finding the price of the final nail. I don't remember if there is a formula for doing a sum of numerous equations. There must be, and I just can't remember it.

When I break out my calculator and do a tedious 3 minutes of punching numbers in, I get a total of $42,949,652.95

Good point. I think the easy way to do it would be to double the cost of the last and subtract one.

(2^(n-1) * 2)-1 = (2^n) -1
(2^32) -1 = 4294967295 (cents)
$42,949,672.95, which agrees with your results.

Edit: I made a typo.

$42,949,672.95

Glatt, a heroic calculation !

But the answer depends on your assumption about "first nail"
1st leg: 1st nail = $0.01 ... 6 nails per shoe = $0.63
2nd leg: 1st nail = $0.01 ... 6 nails per shoe = $0.63
3rd leg: 1st nail = $0.01 ... 6 nails per shoe = $0.63
4th leg: 1st nail = $0.01 ... 6 nails per shoe = $0.63

Total: $2.52
Time to calculate: 15 seconds

That's more like it. This is reminiscent of the puzzler about the wise ass who had some king pay him a penny for the first square on a chess board and two pennies for the second, four for the next, and so on doubling the amount until the King figured out what was going on and had the guy beheaded.

You will have to wait for another nut until tomorrow, but I will off this little puzzle from another, unrelated book.

4 hooves, 8 nails per hoof = 32 nails
2 to the 32 = $42,949,672.95

that's embarrassingly easy. I'm ashamed that I pulled out my calculator to add all those nails up. I should know better.

Edit: Wait a second. That's wrong.

The squirrel is on the tree, and he went around the tree, so yes, he went around the squirrel.

Does Jupiter go around the Earth?

HungLikeJesus · 12-30-2011, 09:50 AM

Is there a treadmill involved?

Does Dark Matter surround Uranus?

This one messes with my space/time/direction dyslexia. I'm sure this ties into my objection to the 'lefty loosy righty tighty' adage, too.

If the squirrel were avoiding the dude in the same direction around the tree, how is he going around the squirrel?

The squirrel is not part of the tree, he's just on the tree.

What if it's a really big tree and the hunter is on the inside?
