To decipher CCXXIX, we add the values of the letters from left to right, with a special rule for subtractive notation. The first C represents 100. The second C also represents 100. The first X represents 10. The second X represents 10. The IX represents 9, where the I (1) is placed before the X (10), indicating subtraction (10 - 1 = 9).
