This is first work if its kind. It brings representations of natural numbers from 0 to 5000 written in terms of single digit “a”. It is in such a way that if we replace a by 1 to 9, it always remains the same. To bring these results only basic operations, such as, *addition*, *subtraction*, *multiplication* and *division* are used. The idea *potentiation* is used in different aspects. See below some examples and links for download the work.
