The numbering system used by the Jihn Wranglikans. Where numbers are presented in exponential units of 9 and the position of the digit is quite significant. When we write “5,” we mean 5 units of 1 each. But when we write “5243” in base 9 instead of base 10, we mean: 5 units of 729 (9x9x9) each, 2 units of 81 (9x9) each, 4 of 9 each, and 3 of 1 each. Which in base 10 would be: 3846
