Zero to 150 in 2003 (Posted on 2002-11-29) Difficulty: 4 of 5
Take the digits 2, 0, 0 and 3. Make equations equating to all the integers from 1 to 150 using these digits according to the following rules:-

a) The above digits are the only digits to be used and no other digits should appear anywhere in the equation (except on the side where the answer will be).

b) Use of any mathematical symbols are allowed.

c) The digits 2, 0, 0 and 3 should appear in the given order in the equation. e.g - 0 + 2 + 3 + 0 = 5 is not acceptable.

d) When using the mathematical symbols try using the most simplest forms as much as possible.

Some Thoughts re: floor? | Comment 31 of 65 |
(In reply to floor? by Happy)

I'm a bit dubious about using floor. Could we use other functions as well then? For example, sin, cos, tan etc.? If so,

hypsin(hypsin(2)) = about 18.78

hypcos(hypcos(2)) = about 21.53

and so on. These are bound to come in useful...
