CCCXI
311 in Roman numerals is CCCXI.

Roman numerals use seven basic symbols: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000. The general rule is: reading left to right, values in descending order add up. When a smaller symbol comes before a larger one, it subtracts (e.g., IV = 4), which does not happen in this case.

Step-by-step conversion of 311:

1. CCC = 100 + 100 + 100 = 300 → C repeated 3 times.

2. X = 10 → represents tens.

3. I = 1 → represents units.

So, 300 + 10 + 1 = 311, or CCCXI in Roman numeral form.

Roman Numeral System Explained

The Roman numeral system uses seven basic symbols to represent numbers:

  • I = 1
  • V = 5
  • X = 10
  • L = 50
  • C = 100
  • D = 500
  • M = 1000

Converting Rules

  • Add the values of the numerals when a smaller numeral follows a larger one (XI = 11)
  • Subtract the smaller of the two numerals from the larger one when a smaller numeral precedes a larger one (IV = 4)
  • Only I, X, and C may be used in subtractive form
  • For numbers 4,000 and above, use vinculum notation: a bar over a numeral multiplies its value by 1,000. For example: V̅ = 5,000, X̅ = 10,000, C̅ = 100,000, M̅ = 1,000,000.
