#PrimeNumbers in #AmazingColourPatterns


n x 10 + m is the formula that describes

  • the ‘digital composition‘ of
    • Leading Digits x 10 + Last Digit
  • of “Digital” Decimal Numbers.

This complements the ‘positional notation‘ of the decimal number system and offers considerable advantages with respect to Digital Visualisations.

With respect to Prime Numbers,

  • the distinction between “Prime Digits” 2 3 5 7 and Prime Numbers > 10 shows
  • that 2 and 5 are the ‘pillars’ of decimal sums and products which is different from
  • the Last Digits 1 3 7 9 that identify Prime Numbers.

“Digital Tables” for Primes

“Digital Tables” for “SemiPrime Series”

The question to be investigated is: what type of numbers are the ones that don’t fit the pattern?

What type of sums or products fill the white spaces?
