MMMDXXI
3,521 in Roman numerals is MMMDXXI.

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 3,521:

1. MMM = 1,000 + 1,000 + 1,000 = 3,000 → M repeated 3 times.

2. D = 500 → represents hundreds.

3. XX = 10 + 10 = 20 → X repeated 2 times.

4. I = 1 → represents units.

So, 3,000 + 500 + 20 + 1 = 3,521, or MMMDXXI in Roman numeral form.

Roman Numeral System Explained

  • X = 10
  • L = 50

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.
