Using the digits in 1996 and any operations (but not mathematical constants), try to write equations that have the numbers from 0 to 100 as the answer.

For example with 1995:

0 = 1*(9-9)*5

2 = (19-9)/5
etc.

Provide as many as you can. Digits 1,9,9 and 6 do not have to appear in order. (But each digit has to be used - 1 and 6 once, 9 twice.)

This is more of a game than a puzzle

(In reply to re(7): Missing numbers by friedlinguini)

If I may serve as an arbiter (sp?) here, I would like to say that I don't consider the use of floor or ceiling functions as breaking (or even bending) of the stated rules.

It all comes down to some sense of mathematical "aesthetics" that people have, and they are understandably more comfortable with functions that they are used to dealing with.

I myself, while I recognize the validity of these functions am more "satisfied" by a solution that avoids their use, as I consider them to be of a higher level than, say, a factorial. And of course there is the notion that the lower level functions you limit yourself to, the more elegant your solution becomes.
