During past years author worked with representations of numbers in terms of 1 to 9 and 9 to 1. These representations called as crazy representations, and are done up to number 300.000. For details refer author's web-sites (site1, site2). This paper brings natural numbers from 300.001 to 340.000 written in ascending and descending orders of 1 to 9 and 9 to 1. The numbers are obtained by using basic operations along with factorials. Few numbers are by use of extra operation square-root. Total work of crazy representations of 200.000 numbers from 300.001 to 500.000 is divided in five parts. This is Part 1. For more details see author's web-site links (link1, link2).
