Regular numbers? Those are for amateurs. Show off your mathematical prowess with a watch that features the equivalent notation of each number. Cheat Sheet (included with each clock): 12  a radical 1  Legendre's constant is a mathematical constant occurring in a formula conjectured by AdrienMarie Legendre to capture the asymptotic behavior of the primecounting 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. The modular multiplicative inverse of 2 (mod 7) is the integer /a/ such that 2*/a/ is congruent to 1 modulo 7. 5  The Golden Mean...reworked a little. 6  Three factorial (3*2*1=6) 7  A repeating decimal that is proven to be exactly equal to 7 with Cauchy's Convergence Test. 8  Graphical representation of binary code. 9  An example of a base4 number, which uses the digits 0, 1, 2 and 3 to represent any real number. 10  A Binomial Coefficient, also known as the choose function. 5 choose 2 is equal to 5! divided by (2!*(52)!) 11 A hexadecimal, or base16, number.
