Here’s a list of Roman numerals:

  • I: 1
  • II: 2
  • III: 3
  • IV: 4
  • V: 5
  • VI: 6
  • VII: 7
  • VIII: 8
  • IX: 9
  • X: 10
  • L: 50
  • C: 100
  • D: 500
  • M: 1000

Remember, Roman numerals are often combined to create other numbers. For example, XV is 15, XX is 20, LX is 60, and so on.

Combination Rules:


Additive Principle: When a smaller numeral follows a larger one, you add their values. E.g., VI = 5 + 1 = 6.

Subtractive Principle: When a smaller numeral precedes a larger one, you subtract the smaller value. E.g., IV = 5 – 1 = 4.

Examples:
VIII: V (5) + III (3) = 8.

XIV: X (10) + IV (4) = 14.

LX: L (50) + X (10) = 60.

CM: C (100) before M (1000) means 1000 – 100 = 900.

MCMXCIV: M (1000) + CM (900) + XC (90) + IV (4) = 1994.

1962 in Roman numerals is MCMLXII

MCM in Roman numerals stands for 1900. The breakdown is:

  • M (1000) + CM (900, which is 1000 minus 100).
