Hello Brilliantics,

Lets make a string of all possible whole numbers by using only FOUR FOURS and +,-,*,%(percentage sign), ^, gamma function, square root , factorial , etc, and you can club the numbers ,that is, you can use 44 or 444 or 4444.

Rule

1) You cannot use any other number but square root and decimal point are allowed
