There are different ways of representing natural numbers, such as writing in terms of 1 to 9 or 9 to 1, writing in terms of single letter, single digit, flexible power, etc. These types of representations we call as crazy representations. This paper bring numbers 30001 to 40000 in terms of digits 1 to 9 separately. For the representations of the numbers from 1 to 30000 refer author's previous works (work1, work2, work3, work4, work5)
