ROMAN NOTATION. 8. In this system seven letters are used to express numbers. Thus,

LETTERS, I, V, X L, C D,
Value, 1. 5.

10.

50. 100. 500. 1000. Other numbers are expressed by writing two or more of these letters side by side.

(1) When a letter is repeated its value is repeated; thus, II represents 2; XXX, 30; CCCC, 400, etc.

(2) When a letter is placed before one of greater value, their Difference is expressed ; thus, IV represents 4; XL, 40; XC, 90, etc.

(3) When a letter is placed after one of greater value, their Sum is expressed; thus, VI represents 6; XV, 15; LX, 60, etc.

(4) A dash placed over a letter increases its value a thousand fold; thus, V represents 5000; VII, 7000; XI, 11000, etc.
