How to write Roman numerals

Switch the keyboard layout to Latin, that is, to English, and click the Caps Lock button (all caps). Now, note that many capital letters of the Latin alphabet can replace Roman numerals.

Let's decide what letters we need:

1. The English letter And, that is - I looks like a unit;
2. Two such letters in a row - II will replace the deuce;
3. Three letters - III, three;
4. In order to write a four, let's call for help the letter B, only English (V), and before it we will not forget to write a one - IV.

I think that the principle of writing has become clear to you, at least up to eight inclusive - VIII. To write nine, we need the letter X (X) with the letter I in front - IX. For fifty, we need the letter - L, for a hundred - C, for five hundred - D, and finally, for a thousand - M.

That is, to write Roman numerals, we only need the Latin alphabet.

How to write in Roman numerals if you don't know how to write them

But what if you are not sure how this or that Roman numeral looks right? For example, you do not know what the number 83 looks like in Roman characters. In order for this method to work, you need the Word program. It is possible that this method also works in other text editors, I don’t know, I personally use Word, and I describe the actions in it.

Hold down the Ctrl + F9 buttons on the keyboard at the same time. In this case, curly braces will appear, and the cursor will be in the center, press the equal sign, the desired number, for example 83 and the left slash, that is, such an oblique line \. Next, put an asterisk, press Caps Lock, and write in English the word - novel, that is, ROMAN and press F9.

Thanks to this formula, Roman numerals are automatically substituted.

I will repeat again:

1. Ctrl+F9;
2. =83\*;
3. cap lock;
4. ROMAN;

This will result in a formula (=83*\roman) which, after pressing the F9 button, is converted into a Roman numeral - LXXXIII.

But personally, it seems to me that it is much faster and more convenient, without any formulas, to substitute capital English letters instead of Roman numerals. Now you know how to write the Roman numeral 1 on a computer or laptop keyboard, choose the method that suits you best.

Only a small part of application developers provide convenient ways to enter Roman numerals using the keyboard in their products. Most programs do not have special functionality for working with a non-positional number system, which requires the user to be smart to enter Roman numerals into them. There are two convenient ways to enter Roman numerals from the keyboard in any program.

Replacing Roman Numerals with English Letters

On any computer, one of the available languages ​​is English by default. You can quickly switch to it using the key combination Alt + Shift or Windows + Space (in Windows 10). The English alphabet completely eliminates the need for a separate numeric keypad for entering Roman numerals, since all their counterparts can be typed using it in capital letters.

The following letters of the English alphabet replace Roman numerals:

• 1 - I;
• 5 - V;
• 10 - X;
• 50 - L;
• 100 - C;
• 500 - D;
• 1000-M.

Even at school, they teach how to use Roman numerals to enter various numbers. The principle is simple: Roman numerals get to the desired number as large as possible suitable in this situation.

For instance:

To enter the number 33, you would need to use 10+10+10+1+1+1.

Accordingly, in the Roman variation, the number 33 will be written as follows: XXXIII.

ASCII is an American coding table that lists the most popular printable and non-printable characters as numerical combinations. To use the characters from this table on a standard keyboard to enter Roman numerals, you must use the NUM number block - located on the right side of the keyboard.

Activate the additional digital block using the Num Lock button. After that, hold down the left ALT on the keyboard and enter combinations of Roman numerals on the right number pad. After entering each character, you need to release ALT so that the character is displayed in the input field. Then again you need to hold down ALT and you can enter the next character.

The following combinations of an additional digital block are identical to Roman numerals:

• ALT + 73 - I;
• ALT + 86 - V;
• ALT + 88 - X;
• ALT + 76 - L;
• ALT + 67 - C;
• ALT + 68 - D;
• ALT + 77 - M.

The method of entering Roman numerals using ASCII codes cannot be called convenient, but it can be used, for example, when the English keyboard layout is disabled for one reason or another.
