XXXVII, CXXXIX, XXIX, XXVI, LXXX, XL, XI Roman Numerals In Numbers

I will be solving some Roman Numerals examples in this article. Roman numerals are the numbers that were used in ancient Rome, which are in base ten and comprise of Latin alphabet (I, V, X, L, C, D and M)

Basic Roman Numerals Rule

• If a bigger letter precedes or comes before a smaller letter, the letters are added. For example: VI = 5 +1 = 6, X1 = 10 + 1= 11, LX = 50 + 10 = 60
• If a smaller letter precedes a bigger letter, the letters are subtracted. For example IV = 5 -1 = 4, IX = 10 – 1= 9, XL = 50- 10 = 40
• If a letter is repeated 2 or 3 times, they are added. For example: CCC = C + C + C = 100 + 100 + 100 = 300
• The same letter cannot be used more than three times in succession.

XXXVII, CXXXIX, XXIX, XXVI, LXXX, XL, XI Roman Numerals

XXXVII = X + X + X + VII (note X is 10 and VII is 7)

XXXVII = 10 + 10 + 10 + 7 = 37

XXVII

XXVII = X + X + VII (note X is 10 and VII is 7)

XXVII = 10 + 10 + 7 = 27

CXXXIX

CXXXIX = C + X + X + X + IX (note C is 100 and IX is 9)

The reason why I put IX together is because a smaller number comes before a bigger number

And IX = 10 – 1 = 9

CXXXIX = 100 + 10 + 10 + 10 + 9 = 139

XXIX

XXIX = X + X + IX = 10 + 10 + 9 = 29

XXVI

XXVI = X + X + V + I (X is 10, V is 5, and I is 1)

XXVI = 10 + 10 + 5 + 1 = 26

LXXX

LXXX = L + X + X + X (note L is 50)

LXXX = 50 + 10 + 10 + 10 = 80

XL

In this case, a smaller number comes before a bigger number. This implies that we will subtract the smaller number from the bigger one.

XL = 50 – 10 = 40

XI

XI = X + I = 10 + 1 = 11

Conclusively, I will make a table representing the values of all the Roman numerals I have discussed.
