In previous works, authors wrote equality expressions in terms of 1 to 9 and 9 to 1 or 9 to 0 separated by single or double equality signs. These expressions are based on the idea of **crazy representations** of natural numbers. These equality expressions are based on basic operations along with **factorial, square-root, Fibonacci sequence** and **triangular numbers values**. These types of equalities, we called as **crazy running equality expressions**. This work is revised and enlarged version of author’s previous works, where the basic operations along with factorial, square-root are considered. It is not possible to write all the natural numbers in terms of **crazy running equality expressions**. Only the possible numbers are written. The work is up to 6 digits:
