The Geek Clock($25) for really geek, where all the numerals have been replaced by the equivalent notation, if you can solve them all.

*12 - the cubed root of 1728*

1 - Legendre's constant is a mathematical constant occurring in a formula conjectured by Adrien-Marie Legendre to capture the asymptotic behavior of the prime-counting function. Its value is now known to be exactly 1.

2 - A joke in the math world: An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third, a quarter of a beer. The bartender says, "You're all idiots," and pours two beers.

3 - A unicode character XML "numeric character reference."

4 - Modular arithmetic, also known as clock arithmetic, is a system of arithmetic for integers, where numbers "wrap around" after they reach a certain value.

5 - The Golden Mean...reworked a little.

6 - Three factorial (3*2*1=6)

7 - Repeating decimal that rounds up to 7.

8 - Graphical representation of binary code.

9 - An example of a base-4 number, which uses the digits 0, 1, 2 and 3 to represent any real number.

10 - A Binomial Coefficient
