Roman Numerals 900 to 1000

Professor Greenline Explaining Math Concepts

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 900 to 1000

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.

How to Write Roman Numerals 900 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

 

By Expansion Method

 

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. 

 

By Grouping Method

 

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.

Rules for Writing Roman Numerals 900 to 1000

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 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.

 

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: CCC = 100 + 100 + 100 = 300 repeating the numeral C 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, 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.

Tips and Tricks in Number Names 900 to 1000

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.

Common Mistakes and How to Avoid Them in Roman Numerals 900 to 1000

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.

Mistake 1

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Repeating numerals more than three times

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Writing numerals more than three times results in mistakes. Children will add it more than three times.

 

For example, writing CM like CCCC by mistake.

Mistake 2

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Confusing addition and subtraction rule

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Kids might get confused with addition and subtraction rules. Instead of adding the number, they might end up subtracting and vice versa.

 

Always remember that a smaller numeral before a larger numeral is subtracted, and a smaller numeral after a larger numeral is added. For example, instead of writing CMXC (990) some children might add the smaller numeral and write it as CMC (1100).

Mistake 3

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Incorrect expansion of numbers

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Breaking the numerals incorrectly will lead to mistakes. Double-check the numerals with the numbers to make sure it is split correctly.

 

For example, for expanding 972 instead of writing it as 900 + 70 + 2, they may write it as 900 + 60 + 12 which gives incorrect numerals. CMXLII instead of CMLXXII.

Mistake 4

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Forgetting the Value of Each Symbol

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

At times, the values of the given symbols can be confusing.

 

For example, D is 500, but if D is confused as 1000, then the whole answer becomes different.

Mistake 5

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Improper Order of Writing the Symbols

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

We will have to write the symbols in the correct order. This will lead to wrong answers.

 

For example, when writing CMXCIX as CMMXCIXX, like instead of writing hundreds in the tens place and vice versa, children make these mistakes.
