- If a smaller numeral is before a larger one, subtract (e.g., IV = 4, IX = 9).
- If a smaller numeral is after or equal, add (e.g., VI = 6, XI = 11).

(1) XLII – XIX

- XLII = 42 (XL = 40, II = 2)
- XIX = 19 (X = 10, IX = 9)
- 42 – 19 = 23
- 23 in Roman numerals = XXIII

✔ Answer: XXIII

(2) XLIX + XXXII

- XLIX = 49 (XL = 40, IX = 9)
- XXXII = 32 (XXX = 30, II = 2)
- 49 + 32 = 81
- 81 = 50 + 30 + 1 = L + XXX + I = LXXXI

✔ Answer: LXXXI

(9) LV + XVIII

- LV = 55
- XVIII = 18
- 55 + 18 = 73
- 73 = 50 + 20 + 3 = L + XX + III = LXXIII

✔ Answer: LXXIII

---

(10) LIV + XV

- LIV = 54 (L = 50, IV = 4)
- XV = 15
- 54 + 15 = 69
- 69 = 50 + 10 + 9 = L + X + IX = LXIX

✔ Answer: LXIX
