The higher roman numerals precede the lower numerals resulting in the correct translation of LXXIX Roman Numerals. In this article, we will explain how to convert LXXIX Roman numerals in the correct number translation.
- LXXIX = L + X + X + (X - I)
- LXXIX = 50 + 10 + 10 + (10 - 1)
- LXXIX = 79
How to Write LXXIX Roman Numerals?
The numerical value of LXXIX Roman Numerals can be obtained by using any of the two methods given below:
Method 1: In this method, we break the roman numerals into single letters, write the numerical value of each letter and add/subtract them.
- LXXIX = L + X + X + (X - I) = 50 + 10 + 10 + (10 - 1) = 79
Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,
- LXXIX = LXX + IX = 70 + 9 = 79
Therefore, the numerical value of LXXIX roman numerals is 79.

What are the Basic Rules to Write Roman Numerals?
- When a bigger letter precedes a smaller letter, the letters are added. For example: CI, C > I, so CI = C + I = 100 + 1 = 101
- When a smaller letter precedes a bigger letter, the letters are subtracted. For example: XC, X < C, so XC = C - X = 100 - 10 = 90
- When a letter is repeated 2 or 3 times, they get added. For example: CCC = C + C + C = 100 + 100 + 100 = 300
- The same letter cannot be used more than three times in succession.

LXXIX Roman Numerals Examples
Example 1: Find the Product of Roman Numerals LXXIX and XLV.
LXXIX = 70 + 9 = 79 and XLV = 40 + 5 = 45
Now, LXXIX × XLV = 79 × 45 = 3555
Since, MMMDLV = 3000 + 500 + 50 + 5 = 3555
Therefore, LXXIX × XLV = MMMDLV
Example 2: Find the Sum of CDXI and LXXIX Roman Numerals.
CDXI = 400 + 10 + 1 = 411 and LXXIX = 70 + 9 = 79
Now, CDXI + LXXIX = 411 + 79 = 490
Since, CDXC = 400 + 90 = 490
Therefore, the sum of CDXI and LXXIX roman numerals is CDXC
Example 3: Find the Difference Between LXXIX and XXXIX.
Roman Numeral LXXIX is equal to 79 and XXXIX is 39.
Now, LXXIX - XXXIX = 79 - 39 = 40
Since, 40 = XL
Therefore, LXXIX - XXXIX = XL
