In the vast majority of cases, Arabic numerals are used to record numbers, formalize calculations and record dates. Their advantage lies in their conciseness and ease of use, since they were specially created for mathematical calculations. At the same time, many numbers are still traditionally written in a Roman numeral system based on letter designations.
Instructions
Step 1
To write units (from one to three), the Latin capital letter "I" is used (read "I", the English analogue - "Ai"). Since ancient times, it was considered the smallest letter in size, and not only in Latin, but in Greek and Old Slavic languages.
Step 2
The letter “V” (“Ve”, the English analogue “Vi”) is used to designate the number 5. The number 4 is written as a combination of one and five (from left to right), that is, in the form of the formula "5-1". The numbers 6, 7, 8 have the form "5 + x", where x is the number of ones to the right of the five.
Step 3
The ten is designated by the letter X ("X", the English version of "Ex"). The number 9 is represented by a formula similar to the formula for the number 4 ("10-1"). 11, 12, 13 are written as a combination of “X” and the corresponding number of units on the right.
Step 4
In the future (up to 50), the numbers are built according to the principle of the first ten: a decrease in a number is indicated by a one on the left, an increase - a one on the right.
Step 5
The number 50 is marked with the letter “L” (“El”, English version “El”). 40 has the form "50 - 10". 60, 70, 80 are depicted according to the principle of the first ten. When using the system, replace
Step 6
The numbers 100, 500 and 1000 are marked with the letters “C”, “D” and “M”, respectively. To decrease or increase a number by one, ten or one hundred, write on the left or right a corresponding letter denoting the number.
Step 7
A complete list of numbers up to a thousand is shown on the table. Please note that the numbers of the lower order are placed on the left if the number is less, and on the right if the number is greater.
