Ever since elementary school I have been prone to making up writing systems and ways of writing down information, be it numbers or words. A few weeks ago, there was a situation at work when I needed to write down a few numbers (names of computers) on the blackboard, but in such a way that certain people could not understand that I am writing them down.

Firstly, I wanted to use Morse code or in Greek numerals, but instead I promptly devised a simple system for smaller numbers that would look puzzling and would probably confuse and discourage anyone from giving it much thought. And so it was. Those "symbols" that I have written on the board looked like a sort of doodle and numbers behind them remained hidden until it was time for me to retrieve them.

For now, I like to call it the Milantex Numbering System. I know... it may be "a bit [pick a word]", but I do not care.

Milantex Number System MatriceThe numerical system supports numbers from 1 to 99,999, even though initially it was used to write numbers up to 130. Afterwards, I have revised my initial numerical system "doodle" and the final version looks and works as follows.

A complete "matrix" of possible lines, dots and other elements of the numerical part writing all written at once one on top of the other creates a schematic is shown on the right.

Normally, a number looking like this can never exist, because some segments cannot coexist one with the other in one number representation and are excluded or replaced when the sequence is properly formed. Instead of explaining the mathematics behind the idea, I will give a small table of examples of numbers written in the number system.

Hopefully, the displayed numbers in this table will give anyone who pays attention and has a keen eye the idea on how the system works. For those who do not see or do not want to bother analysing the table I have created a simple JavaScript tool to convert any number from 1 to 99,999 written in decimal base into this odd and invented number system. I don't believe that I have to mention that the system does not support decimals, but it might at some point, if I decide to mess around with its further development.

For now, it will remain accidentally derived fun thing, born out of the need for concealment.
