How to play

  1. I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000.
  2. Add the values from left to right, biggest first.
  3. When a smaller numeral comes just before a bigger one, take it away: IV = 4, IX = 9, XL = 40.

What it exercises

Place value from a different angle. Roman numerals have no zero and no columns, so you see why our way of writing numbers is so handy.
