Which of these represents a perfect SAT score in Roman numerals?
Answer: Roman numerals, the numeric system of ancient Rome, uses combinations of letters from the Latin alphabet to signify values. They are composed of seven Latin letters. They are, in this order, from lower to higher: I (one), V (five), X (ten), L (fifty), C (one hundred), D (five hundred), and M (one thousand). The maximum score on the SAT is a 1600. To convert 1,600 to Roman Numerals you need to split it up into place values (ones, tens, hundreds, etc.) You then combine them all together to get MDC.
The numeric system represented by Roman numerals originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Wikipedia
