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.

Presumably one could also use inverse tan (-1) to be 135 (in degrees). With this and the integer above and below functions I managed 120 to 150 pretty easily. Some edited highlights include
150= intabove(sqrt(200)) + invtan(-intbelow(sqrt(3)))
146= (2+0!)! + invtan(-0!) + intbelow(sqrt(sqrt(3!!))
145= intbelow(sqrt(20)) + invtan(-0!) + 3!
The rest dropped out without quite so much convoluted faffing about. I guess this just leaves 104 to 120 which shouldn't be too bad.
