Check MCMXLI by reading it back

Reading MCMXLI from left to right and adding the pieces: M = 1000, CM = 900, XL = 40, I = 1. Together that is 1000 + 900 + 40 + 1 = 1941, so MCMXLI and 1941 match.

  • Read MCMXLI as one number, not letter by letter: add the values left to right, except where a smaller symbol sits before a larger one.
