Roman Numerals are the symbols from the Latin letters used by Romans for daily transactions and counting purposes. In this topic, we will learn how to write Roman Numerals and their uses.
Roman Numerals use symbols to represent number systems. Ancient Romans used the letters I, V, X, L, C, D, and M to represent the number system.
The unavailability of zero at that time and the lack of other mathematical operations made the Roman Numerals obsolete in recent times. For example, we write 950 as CML.
Roman numbers are used today in clocks, chapters in books, classrooms, etc. The following chart helps us to understand the numerals better. List of Roman Numerals 900 to 1000 The list of Roman Numerals provides an organized way to understand how those letters combine to represent a number.
The given list starts from CM (900) to M (1000). Learning these numerals helps you in a deeper understanding of the numerical system.
Roman Numerals from 900 to 910
Roman Numerals from 911 to 920
Roman Numerals from 921 to 930
Roman Numerals from 931 to 940
Roman Numerals from 941 to 950
Roman Numerals from 951 to 960
Roman Numerals from 961 to 970
Roman Numerals from 971 to 980
Roman Numerals from 981 to 990
Roman Numerals from 991 to 1000
Roman Numerals rely on specific symbols, and it has rules of addition and subtraction. The basic symbols in Roman Numerals are: I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M = 1000 Using the above symbols, we can combine the Roman Numerals for the numbers easily.
There are two basic methods of writing Roman Numerals, they are By Expansion Method By Grouping
Through the expansion method, we break down the numbers into hundreds, tens, and ones parts and then convert them into numerals.
Step 1: Break the numbers into ones, tens, and hundreds parts.
Step 2: Write Roman Numerals for each part.
Step 3: Combine all the parts to get the numerals.
Example: For the number 999.
Step 1: Break the numbers 900 + 90 + 9 = 999
Step 2: Add Roman Numerals for each part The Roman Numeral of 900 is CM. The Roman Numeral of 90 is XC. The Roman Numeral of 9 is IX.
Step 3: Combine all the parts 900 (CM) + 90 (XC) + 9 (IX) = CMXCIX. Therefore, the Roman Numeral of 999 is CMXCIX.
Grouping method directly from the number by combining Roman Numeral symbols directly. It uses addition and subtraction rules.
Step 1: Start writing numerals for the largest number.
Step 2: Smaller numbers are either getting added or subtracted.
Following the rule of adding and subtraction is mandatory.
Addition: smaller numeral after the larger numeral.
Subtraction: smaller numeral before the large numeral. Example: For the number 912.
Step 1: Start with the larger numbers. While splitting, we will get 900 and 12 The Roman Numeral of 900 is CM
Step 2: Add or subtract the smaller number If we add 12 to 900 it will become 912. The Roman Numeral of 12 is XII Therefore, the Roman Numeral of 912 is CMXII.
Roman Numerals follow rules to make sure the number is written correctly. Here are some main rules given below
Rule 1: Addition Method
Rule 2: Repetition Method
Rule 3: Subtraction Method
Rule 4: Limitation Rule
In Roman Numerals, if the smaller numeral comes after the large numeral, then we need to add their values. Example: If the given number is CML. We can see that the number CM refers to 900 and the other number refers to 50. So in this, the smaller numeral is after the large numeral, so we need to add the 900 and 50 to get the value 950.
The Roman Numeral can be repeated up to three times to increase its value. The numbers cannot be repeated after three times. Only symbols like I, X, C, and M can be repeated and V, L, and D cannot be repeated. Example: CCC = 100 + 100 + 100 = 300 repeating the numeral C for the fourth time is not allowed.
If the smaller numeral comes before the large numeral, then we need to subtract the smaller numeral from the larger numeral to get the number. There are three rules in subtraction, they are, I can be subtracted from V and X. X can be subtracted from L and C. C can be subtracted from D and M. Example: In the number CM. Here, M is the biggest numeral and C is the smallest numeral. As we see that the smaller numeral is before the larger numeral, we need to subtract to get the number. M (1000) - C (100) = CM (900).
Roman Numerals consist of several limitations, they are: A numeral cannot be repeated more than three times. For example, III (3) cannot be repeated more than 3 times, instead we use IV for writing 4. Subtraction cannot be done with the non-pair numbers. For example, XI here X (10) - I(1) gives IX is applicable but IC, C (100) - I(1) is not applicable. Only one subtraction can be allowed in one numeral. For example, XL (40), L (50) - X (10) is applicable to get 40 but XXL is not applicable to get the number 30.
Roman Numerals are fun to learn and easy to write when you know the following tips and tricks.
It is easy to make mistakes while learning Roman Numerals, but using the following mistakes and the ways to avoid them can help you to avoid those mistakes.
Write the Roman Numerals for 928 using the breakdown method.
The Roman Numeral of 928 is CMXXVIII.
Step 1: Break the numbers into hundreds, tens, and ones. 928 = 900 + 20 + 8
Step 2: Add numerals to each part. The Roman Numeral of 900 is CM. The Roman Numeral of 20 is XX. The Roman Numeral of 8 is VIII.
Step 3: Combine the parts 900 (CM) + 20 (XX) + 8 (VIII) = CMXXVIII (928).
Add CM + LVI.
CMLVI
Adding CM (900) and LVI (56) = CMLVI (956).
Subtract M - XXV.
CMLXXV
M = 1000 XXV = 25 1000 - 25 = 975 = CMLXXV.
Write the Roman Numeral of 1000.
M
The Roman Numeral of 1000 is M.
Add 950 + 45 and write the answer in Roman Numeral.
CMXCV
950 + 45 = 995 CML + XLV = CMXCV.
