In 2013-2014, author (click here<\/a>) wrote natural numbers in increasing and decreasing orders of 1 to 9 using only basic operations<\/strong>. See below some examples:<\/p>\n\n\n

The above work is up to natural numbers 300.000. More details are in the following two links<\/p>\n\n\n\n

  2. Crazy Representations of Natural Numbers From 280001 to 300000 (zenodo.org)<\/a><\/li>\n<\/ol>\n\n\n\n

    According to Link 1<\/a> <\/strong>we can write only with basic operations, the numbers up to 10957. The first number 10958 is not possible to write only with basic operations. Here we need some extra functions, such as factorial, square root etc. <\/p>\n\n\n\n

    The aim here is the write the numbers up to 10.000 with distinct functions, such as, square-root, factorial, quadratic (square), cubic, Triangular and Fibonacci<\/strong>, etc. See below two examples of numbers 100 and 218 written in six separate ways.<\/p>\n\n\n
