Roman numerals are an ancient system that uses letters from the Latin alphabet to represent numbers. Here's a breakdown:
- I (one) ποΈ
- V (five) β
- X (ten) π
- L (fifty) π
- C (one hundred) π―
- D (five hundred) π‘οΈ
- M (one thousand) π
Basics of Roman Numerals
Understanding Roman numerals involves knowing how to use these symbols:
- Symbols are typically added together when they're in descending order (e.g., VIII = 8).
- When a smaller numeral appears before a larger one, it's subtracted (e.g., IV = 4).
Tips for Conversion
- Additive Rule: Add symbols when they are in order (e.g., XXIV = 24).
- Subtractive Rule: Subtract when a lower numeral precedes a higher one (e.g., XIX = 19).
- Roman numerals never use the same symbol more than three times in a row (except for M).

Conversion Steps:
-
Read from Left to Right:
- Start with the highest place value, M which means 1000, and add two more (MMM) for 3000.
- Next, CM stands for 900, derived from 1000 (M) minus 100 (C), equalling 900.
- LXXIX can be broken down as 50 (L) + 20 (XX) + 9 (IX), which sums to 79.
-
Combine the Numerals:
- MMM (3000) + CM (900) + LXXIX (79) = 3979. Since we want 1979, we have:
- M + CM + LXXIX = 1000 + 900 + 79 = 1979.
- MMM (3000) + CM (900) + LXXIX (79) = 3979. Since we want 1979, we have:
