These seven letters, combined according to the following rules, serve to express all numbers what ever. 1. If a letter be repeated, its value is also repeated thus, II stands for two; III for three; XX for twenty; CCC for three hundred. 2. If a letter be placed after another of greater value, its value is united to that of the greater—thus, XI stands for eleven; XIII for thirteen; LX for sixty; DCC for seven hundred. 3. If a letter be placed before another of greater value, its value is taken from that of the greaterthus, IX stands for nine; XL for forty; XC for ninety; CD for four hundred; CM for nine hundred. 4. If a letter be placed between two other letters of greater value, its value is taken from the number expressed by the other two-thus, XIV stands for fourteen; XIX for nineteen; CXL for one hundred and forty. 5. A letter with a line drawn over it expresses as many thousands as the letter itself expresses units; thus V stands for five thousand; X for ten thousand; C for a hundred thousand. Examples.
