The shape of CLI

  • Written out, CLI runs 3 characters, against 2 for 150 (CL) and 4 for 152 (CLII).
  • No part of CLI is subtractive: each glyph adds to the running total, so the numeral reads straight through from left to right.
  • Every number from 100 to 199 opens with C, so it is the LI after C that marks 151 out as 51 past 100.
  • CLI uses 3 different symbols and repeats none of them: one appearance each.
