Roman numerals were used in Europe before Arabic numerals were adopted. Roman numerals use seven Roman letters, namely, I (1), x( 10), C( 100), Male (1000), V(5), L(50) and D(500). Calculation method: (1) Conjunction of the same number, the number of which is equal to the sum of the numbers represented by the obtained data, for example, Ⅲ = 3; (2) A few large numbers on the right are equal to obtain the numbers represented by these numbers, and the added numbers, for example, ⅷ = 8, =12; (3) A small number (limited to I, X and C) and a large number are left, and the number is reduced to be equal to the number represented by a large number, for example, Ⅳ = 4, ⅸ = 9; (4) Draw horizontal lines on some of them, indicating the value of the times, the number 1000, the number of rules set by Roman numerals = 12000, and others must be mastered; (1) The elementary form of the basic numbers Ⅰ, x and c, or the large form of any number used together on the right, cannot exceed three; Large numbers can only be used in the one on the left. (2) The basic numbers V, L, D cannot be added or subtracted by the number on the left side of the table; Only one number can be used for a large sum used correctly. (3) A few people in V and X can only use the I on the left. (4) A few can only use X on the left side of L and C, and a few can only use three Roman numerals on the left side of D and M, which is very troublesome, so it has not been used up. Published in China, Roman numerals are mainly used for some codes, such as product types. The computer ASC code contains appropriate Roman numerals ranging from 1 to 12.
