What do you think of Roman numerals? What are the numbers of Roman numerals?

Roman numerals are a type of numeral used in Europe before the introduction of Arabic numerals. Roman numerals are numerals with seven Roman letters, namely (1), X (10), C (100), M (1000), V (5), L (50), D (500). How to count:

1) The same number is written in a row, and the number represented is equal to the number obtained by adding these numbers, e.g., = 3;(2) The small number is to the right of the large number, and the number represented is equal to the number obtained by adding these numbers, e.g., = 8, = 12;(3) Small numbers, (limited to , x, and c) to the left of large numbers, represent a number equal to the number obtained by decreasing the large number, e.g., = 4, = 9;(4) Draw a horizontal line on top of a number, indicating that the number has increased by 1 000 times, such as = 12 000. There are several rules for the number of Roman numerals that need to be mastered; (1) Any one of the basic numbers, x, and c cannot be used in conjunction with the constituent number by itself, or placed on the right side of the large number, and the constituent number shall not exceed three; Only one can be used to the left of a large number. (2) Do not put any of the basic numbers v, l, and d as a decimal number to the left of the large number, and use the method of subtraction to form a number; To the right of a large number, the number is added to form a number, and only one can be used.

3) The small numbers to the left of v and x can only be used. (4) The small digits to the left of L and C can only be used. (5) The small digits to the left of d and m can only be used with c.

Keeping up larger numbers with Roman numerals is very cumbersome, so it's not commonly used anymore. In Chinese publications, Roman numerals are mainly used for certain **, such as product models, etc. The computer ASC code contains the combined Roman numeral 1 12.

What is the difference between = 12 000 and = 12? Why is one = 12000 and another = 12?

Take 1 10 as an example.

The corresponding Roman numerals are i

ii, iii, here's a way to make it easier to memorize other numbers:

v stands for 5, x stands for 10, and putting i to the left of these letters represents the value minus 1, e.g. lv for 4 (5-1) and lx for 9 (10-1).

Conversely, put L on the right side to represent addition, such as VL for 6 (5 + 1), VLL for 7 (5 + 2), and XL for 11 (10 + 1).

So remember the key letter to represent the number, and the rest should be remembered:

v,5x,10

l,50c,100

d,500m,1000

Rote. If you understand it, you can understand it, even if you don't understand it, I'm like this!

Not good, much worse than Arabic numerals!

It's Roman numerals.

Roman numerals 0-9: I(1), II(2), III(3), IV(4), V(5), VI(6), VII(7), VIII(8), IX(9), X(0).

Roman numerals -xiii, 14-xiv, 15-xv, 16-xvi, 17-xvii, 18-xviii, 19-xix, closed 20-xx.

I, IV, III, II, IIV are Roman numerals.

The corresponding Arabic numerals, which are now internationally accepted, are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

Roman numerals can be typed by opening the soft keyboard.

Roman numerals, a type of numeral used in Europe before the introduction of Arabic numerals (which are actually Indian numerals), are now less commonly used. It was produced later than the digits in the Chinese oracle bone inscriptions, and even later than the decimal digits of the Egyptians.

The most common Roman numerals are the dial symbols of clocks: , iiii).

Periodic table: Ia, IIA, IIIA, IVA, VA, VIA, VIIA, IB, IIB, IIIB, IVB, VB, VIB, VIIB, VIIII.

Counting method. 1) The same number is written in a row, and the number represented is equal to the number obtained by adding these numbers, e.g., = 3;

2. The small number is to the right of the large number, and the number represented is equal to the number obtained by adding these numbers, such as: 8;Sakura lead = 12;

3. Small numbers, the ridge is good (limited to , x and c) to the left of the large number, and the number represented is equal to the number obtained by decreasing the large number, such as: =4;ⅸ=9；

4. During normal use, the number written in a row shall not be repeated more than three times. (Exception to the four o'clock "IIII" on the dial).

5. Draw a horizontal line on top of a number, indicating that the number is expanded by 1000 times.

It's Roman numerals.

Roman numerals are a type of numeral used in Europe before the introduction of Arabic numerals, which are now less widely used. It was produced later than the digits in the Chinese oracle bone inscriptions, and even later than the Egyptian ten-core base numerals. However, its creation marked the progress of an ancient civilization.

In July 2015, Rome, Italy, said it would abandon the use of Roman numerals and change street signs and official documents to Italian.

Roman numerals are numerals with seven Roman letters, namely (1), X (10), C (100), M (1000), V (5), L (50), D (500).
