Roman Numerals 1000 to 2000

Roman Numerals use symbols to represent number systems. Ancient Romans used the letters I, V, X, L, C, D, and M to represent numbers.

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 1500 as MD.

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 1000 to 2000 The list of Roman Numerals provides an organized way to understand how those letters combine to represent a number.

The given list starts from M (1000) to MM (2000). Learning these numerals helps you in a deeper understanding of the numerical system.

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 Method

By Expansion Method

Through the expansion method, we break down the numbers and then convert them into numerals.

Step 1: Break the numbers into manageable parts.

Step 2: Write Roman Numerals for each part.

Step 3: Combine all the parts to get the numerals.

Example: For the number 1999.

Step 1: Break the numbers 1000 + 900 + 90 + 9 = 1999

Step 2: Add Roman Numerals for each part The Roman Numeral of 1000 is M. 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 1000 (M) + 900 (CM) + 90 (XC) + 9 (IX) = MCMXCIX. Therefore, the Roman Numeral of 1999 is MCMXCIX. 

By Grouping Method

Grouping method directly forms the number by combining Roman Numeral symbols. 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 1200.

Step 1: Start with the larger numbers. While splitting, we will get 1000 and 200 The Roman Numeral of 1000 is M

Step 2: Add or subtract the smaller number If we add 200 to 1000 it will become 1200. The Roman Numeral of 200 is CC Therefore, the Roman Numeral of 1200 is MCC.

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

Rule 1: Addition Method

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 MCC. We can see that the number M refers to 1000 and the other numbers refer to 200. So in this, the smaller numeral is after the large numeral, so we need to add the 1000 and 200 to get the value 1200.

Rule 2: Repetition Method

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: MMM = 1000 + 1000 + 1000 = 3000 repeating the numeral M for the fourth time is not allowed.

Rule 3: Subtraction Method

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).

Rule 4: Limitation Rule

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, XC here X (10) - C(100) gives XC is applicable but IC, C (100) - I(1) is not applicable. Only one subtraction can be allowed in one numeral. For example, CM (900), M (1000) - C (100) is applicable to get 900 but CCM is not applicable to get the number 800.

Roman Numerals are fun to learn and easy to write when you know the following tips and tricks.

• Memorize the basic symbols like I (1), V (5), X (10), L (50), C (100), D (500), and M (1000), to write and read the other numerals easily.
   
• Always break the big numerals into smaller parts to make it easier to read and write.
   
• Remember the repetition rule, a number should not be added more than three times.
   
• Practice the smaller numerals and gradually move to the bigger values.
   
• We use numerals in clocks, classrooms, etc., and try to read from the numeral clock to make numerals easy to learn.

• Expansion Method: The process of breaking down numbers into smaller parts to convert them into Roman Numerals.

• Grouping Method: A method to form Roman Numerals directly using addition and subtraction rules.

• Repetition: Using the same symbols more than once, but not more than three times. For example, MMM for 3000.

• Addition Method: Adding values when a smaller numeral comes after a larger numeral.

• Subtraction Method: Subtracting values when a smaller numeral comes before a larger numeral.
