The Arabs invented a convenient and compact system of noting numbers, which is now used by the whole world. However, there are and have been alternative ways of writing numbers, individual for each nation. For the most part, they are based on the letters of the alphabet. One of these systems exists and is still used today - the system of Roman numerals.
Instructions
Step 1
To write Roman numerals, capital letters of the Latin alphabet. When working on a computer, you do not need to additionally install anything in the language bar, English is enough - all the characters necessary for entering Roman numerals are present there.
Step 2
Memorize the basic letters corresponding to Roman numerals and numbers up to 1000.
I (corresponds to the English "Ay") - 1. There is some similarity in spelling between the Roman and Arabic numerals, so there should not be much difficulty.
V (English "V") - 5.
X (English "Ex") - 10.
L (English "El") - 50.
C (English "C") - 100. Since in the Latin alphabet this letter was read as "C", remember it as the first letter in the word "centner" - 100 kg.
D (English "D") - 500.
M (English "Em") - 1000.
Step 3
Numbers 4 and 9 are designated as "5-1" and "10-1", respectively. When written, it looks like this: IV and IX (the unit is written to the left of the larger number). Accordingly, numbers 1, 2, 3 units more than five or ten are written in the form of the formula "5 + x", "10 + x" (units are written to the right of the larger number, x is equal to the number of units): VI, XIII.
Step 4
The numbers 40 and 90 are written using a similar formula, but tens are used instead of units: XV, XC. When writing numbers 60 and 110, the letter denoting the lower number is written on the right. Hundreds and thousands are recorded according to the same principle.
Below is a complete table of numbers from one to a thousand in the Roman system.
