How to read the chart

Read each row as a decade. The ones repeat the same ten patterns in every row (I, II, III, IV, V, VI, VII, VIII, IX) after the tens part, so 37 is XXX + VII = XXXVII and 87 is LXXX + VII = LXXXVII. The tens follow the same shape one rank up: X, XX, XXX, XL, L, LX, LXX, LXXX, XC.

The columns ending in 4 and 9 are where subtraction appears: IV, IX, XIV, XIX, and so on. Forty and ninety subtract too, which is why 49 is XLIX and 99 is XCIX rather than IL or IC. The rules page explains why.

Grouped by hundreds. Hundreds work like tens and ones: C, CC, CCC, CD, D, DC, DCC, DCCC, CM, and 1000 is M.
