Here’s a breakdown of how the Roman numeral “MCMXXX” is constructed:

  • The first symbol, “M”, represents 1000.
  • The next symbol, “CM”, represents 900. This is because “C” (100) is placed before “M” (1000) and subtracted from it, leaving 900.
  • The third symbol, “XXX”, represents 30. This is because “X” (10) is repeated three times to get 30.

So altogether, “MCMXXX” represents 1000 + 900 + 30 = 1930.

Before the adoption of the Arabic numeral system, Roman numerals were widely used, particularly in the Roman Empire and throughout medieval Europe.
