How to write the Roman numeral MMMCMXCI in numbers
Writing the Roman numeral MMMCMXCI in Indo-Arabic numbers isn’t difficult if you know the basics of the Roman number system and some basic math, such as which Roman sign represents what value and how to do addition and subtraction.
Basics of Roman numerals:- Roman numerals represent a number based on seven letters or symbols. These letters are I, V, X, L, C, D and M. In this system, I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, and M = 1000.
Now let’s see how you can convert MMMCMXCI to numbers in just four steps.
First of all, break down MMMCMXCI as below.
MMMCMXCI = M, M, M, C, M, X, C, I
Then replace the Roman symbols with their equivalent values.
M, M, M, C, M, X, C, I = 1000, 1000, 1000, 100, 1000, 10, 100, 1
Here comes the tricky part. Read the numbers from left to right. If you find a number greater than the previous number, then subtract the previous number from it (e.g., 100, 10, 50 = 100, (50-10) = 100, 40).
1000, 1000, 1000, 100, 1000, 10, 100, 1 = 1000, 1000, 1000, (1000 - 100), (100 - 10), 1 = 1000, 1000, 1000, 900, 90, 1
In the final step, add the numbers together.
1000, 1000, 1000, 900, 90, 1 = 1000 + 1000 + 1000 + 900 + 90 + 1 = 3991
Here’s a table for better understanding.
| Roman Symbols | Indo-Arabic Number |
|---|---|
| MMM | 3000 |
| CM | 900 |
| XC | 90 |
| I | 1 |
| MMMCMXCI | 3991 |
