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

+- -+
