MCMXXI Roman Numerals

MCMXXI Roman Numerals can be written as numbers by combining the transformed roman numerals i.e. MCMXXI = M + CM + XX + I = 1000 + 900 + 20 + 1 = 1921. The higher roman numerals precede the lower numerals resulting in the correct translation of MCMXXI Roman Numerals. In this article, we will explain how to convert MCMXXI Roman numerals in the correct number translation.

• MCMXXI = M + (M - C) + X + X + I
• MCMXXI = 1000 + (1000 - 100) + 10 + 10 + 1
• MCMXXI = 1921

How to Write MCMXXI Roman Numerals?

The numerical value of MCMXXI 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.

• MCMXXI = M + (M - C) + X + X + I = 1000 + (1000 - 100) + 10 + 10 + 1 = 1921

Method 2: In this method, we consider the groups of roman numerals for addition or subtraction such as,

• MCMXXI = M + CM + XX + I = 1000 + 900 + 20 + 1 = 1921

Therefore, the numerical value of MCMXXI roman numerals is 1921.

What are the Basic Rules to Write Roman Numerals?

• When a bigger letter precedes a smaller letter, the letters are added. For example: XI, X > I, so XI = X + I = 10 + 1 = 11
• When a smaller letter precedes a bigger letter, the letters are subtracted. For example: IV, I < V, so IV = V - I = 5 - 1 = 4
• When a letter is repeated 2 or 3 times, they get added. For example: II = I + I = 1 + 1 = 2
• The same letter cannot be used more than three times in succession.
