### Eleventy-One

Eleventy-One,

111 or One hundred and eleven as it is more commonly (and more boringly) known is a number created by J. R. R. Tolkien in

The Lord of the Rings. 111 is also known as one-eleven, as in the

European Unions reciprocial health care agreement, the

E111. This has nothing at all to do with the

reciprocal of 111, which is

^{1}/

_{111}, or

. .
0.009

Of course, to really

confuse people, write it as 111

^{-1}, since most people don't know that x

^{-1} means the reciprocal of x.

#### Interesting Maths (a contradiction in terms)

111/111 11/11 1/1 is 1 1 1 is eleventy one

Eleventy One has eleven letters.

111

^{2} is 12321.

111 - 42 is a sex act.

111 is not prime: 37 x 3 = 111

The devils number has 111 as a

factor
111 x 910 gives 101010 : the

binary for 42

111 is approximately equal to 42 (an error of only 62.1% - good for a

physics experiment)

111 has a nice binary representation: 1101111. As does 42 (101010). If 42 is uncertain (yes, no, yes, no, yes, no) then 111 is almost certain (well...

^{6}/

_{7} of the time!)
