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.

You have a very nice start on your list.

In my list, I try to minimize the number of operators and functions used in the expression. Your list had some entries using fewer functions than mine. I updated my list with some entries from your list and gave you credit. (11 entries) I am still deciding on the decimal point and the subfactorial, but I will probably put them in.

There are symbols for floor and ceil. Floor and ceil each have a pair of symbols. Unfortuneately, I can not find a font with those symbols.

ceil


+-   -+


| 2.1 | =3





floor


| 2.9 | =2


+-   -+
