How to Write 1800 in Roman Numerals?

Writing 1800 in Roman numerals involves writing it in expanded form to replace each number with the respective symbol and combining them using the additive rule of Roman numerals.

Let's understand it step by step:

1. Break the number into parts: 1800 = 1000 + 500 + 100 + 100 + 100

2. Write Roman numerals for each part: 1000 = M, 500 = D, C = 100

3. Add them together: M + D + C + C + C = MDCCC

4. So, 1800 is MDCCC in Roman numerals.

Basic Rules of Writing Roman Numerals

• Repetition Rule: A symbol can be repeated only 3 times.
  Example: XX = 20, CC = 200
  A symbol is added to itself if repeated.
  Example: III = 3, XXX = 30

• Subtractive Rule: If a smaller symbol precedes a larger one, we subtract.
  Example: IX = 10 – 1 = 9

• Additive Rule: If a smaller symbol comes after a bigger one, we add.
  Example: VI = 5 + 1 = 6

• Symbols V (5), L (50), and D (500) are never repeated and never subtracted.

• I can be subtracted only from V and X and X can be subtracted only from L, C, and M.
  
  

Solved Examples on 1800 in Roman Numerals 

Example 1: Write the sum of MCC (1200) and  DC (600) in Roman numerals.

Solution: MCC = 1200 and DC = 600

By adding the numerical value of MCC and DC, we get: 1200 + 600 = 1800

1800 in Roman numerals = MDCCC

Example 2: Subtract DC (600) from MMCD (2400).

Solution: DC = 600 and MMCD = 2400

By subtracting 600 from 2400, we get: 2400 – 600 = 1800

1800 in Roman numerals = MDCCC

Example 3: Multiply CM (900) by II (2).

Solution: Let's multiplying 900 by 2 to ge the result

900 × 2 = 1800

1800 in Roman numerals = MDCCC

Example 5: Divide MMMDC (3600) by II (2).

Solution: 3600 ÷ 2 = 1800

Roman numerals = MDCCC
