The ancient Romans in their notation made use of the following seven
letters; viz. I. V. X. L. C. D. and M. which singly stood for one,
five, ten, fifty, one hundred, five hundred, and one thousand. By
repeating and combining these any other numbers were formed.
The _annexing_ a less number to a greater increases its value, and
denotes the sum of both; as VI. signifies six. The _prefixing_ a less
number to a greater lessens its value, or shews their difference;
thus, IV. is four, &c. The word thousand is often expressed by a line
drawn over the top of a number; thus, X̅. signifies ten thousand.
