CCLXXXIV

In ancient Rome, the numeral system used a combination of letters to represent numbers. The letters I, V, X, L, C, D, and M were used to represent the numbers one, five, ten, fifty, hundred, thousand, and ten thousand, respectively. To represent larger numbers, the Romans used subtractive notation, in which the symbols for smaller numbers were placed within those for larger numbers to indicate subtraction. For example, IV represents four, because V represents five and I represents one.

The CCLXXXIV numeral also has its own distinct way of conversion to the base 10 number 284. CCLXXXIV could be broken into its more commonly known Roman numeral equivalents, which are C as the hundred's place, CC as the tens place (going up by multiples of 10), and LXXX IV as the units place. C represents 100, CC represents 200, LXXX represents 80, and IV represents 4. All these being added up means one equation of C+CC+LXXX+IV = 284, effectively validating the non-mnemonic use of CCLXXXIV.
