The Roman number is a number system that was used by the ancient times Romans to count and perform various everyday activities. The alphabet used to define or to present the roman numbers are the alphabets of Latin.

As the numbers reach 10, it becomes hard to count on fingers. That’s when there was a need to create a system that could help in trade and communications.

Seven letters represent modern Roman numbers, which help in writing different numbers. The letters I, V, X, L, C, D, and M represent the integer values of 1, 5, 10, 50, 100, 500, and 1000. After learning the rules for writing them, Roman numbers 1 to 100 become easy.

The Method of Writing Numbers to Roman Numeral

There are two ways to write down the Roman numbers 1 to 100.

Method 1: Breaking the particular number into a form that is easier to convert it into a roman number.

For instance, let’s take the number 65.

Now let’s try breaking the numbers 65 = 50 + 10 + 5 = L + X + V = LXV.

Method 2: Number grouping for addition.

For example, 85 = 80 + 5 = LXXX + V = LXXXV

These two methods can be used while writing roman numbers 1 to 100.

Rules for Writing Roman Numerals

Certain rules are to be followed while writing the roman numbers 1 to 100. The rules are as follows:

The bigger letter numbers are written first and the smaller letter ones are added.

For example: CL, C ＞ L, so C + L = 100 + 50 = 150 = CL

If a smaller roman number precedes a bigger roman number, it subtracts.

For example: IX, I ＜ X, so X – I = 10 – 1 = 9 = IX

If a letter is repeated multiple times, it adds.

For example: XXX = X + X + X = 10 + 10 + 10 = 30 = XXX

We cannot repeat the same letter more than three times.

Letters like V, L, and D shouldn’t be repeated unlike X and I’s.

The roman number system to represent the numbers was developed in 500 b.c by the Romans. As the Romans ruled most of the world, their number system was used throughout Europe. Roman numbers were used as a primary manner to represent numbers for centuries.

For writing roman numbers, we need to convert the numbers by breaking up them based on their place values. For example, let’s say you need to convert the number 65.

The Roman number is a number system used by the ancient Romans to count and perform various everyday activities.
