"Read and Write Roman Numerals to 100 Answers" from
Math-Salamanders.com, which includes two sections:
---
✔ Section 1: Convert Roman Numerals to Numbers
Convert each Roman numeral into its Arabic (standard) number.
| Roman Numeral | Answer |
|---------------|--------|
| 1) XVII | 17 |
| 2) XX | 20 |
| 3) XIV | 14 |
| 4) XXV | 25 |
| 5) LI | 51 |
| 6) XL | 40 |
| 7) XXXVII | 37 |
| 8) LXII | 62 |
| 9) XLVI | 46 |
| 10) XC | 90 |
| 11) LXXIII | 73 |
| 12) C | 100 |
| 13) XXIX | 29 |
| 14) XCVII | 97 |
✔ Explanation of Key Rules:
-
I = 1, V = 5, X = 10, L = 50, C = 100
- When a smaller numeral appears
before a larger one, it's
subtracted.
- e.g., IV = 4 (5 - 1), IX = 9 (10 - 1), XL = 40 (50 - 10)
- When smaller numerals follow larger ones, they are
added.
- e.g., VI = 6 (5 + 1), XVI = 16 (10 + 5 + 1)
Let’s verify a few:
-
XVII = 10 + 5 + 1 + 1 =
17
-
XL = 50 - 10 =
40
-
XC = 100 - 10 =
90
-
C =
100
-
XCVII = 100 - 10 + 5 + 1 + 1 =
97
All answers in this section are correct.

| 12) 59 | LIX |
| 13) 90 | XC |

✔ Explanation of Key Conversions:
-
13 = 10 + 3 → X + III =
XIII
-
9 = 10 - 1 →
IX
-
19 = 10 + 9 → X + IX =
XIX
-
41 = 40 + 1 → XL + I =
XLI
-
28 = 20 + 8 → XX + VIII =
XXVIII
-
59 = 50 + 9 → L + IX =
