What Is a Number?

A number is an arithmetic value used to represent some quantity of things. The numbers help in making calculations. The mathematical symbol that represents some number is known as a numeral.

For example, 5 represents some arithmetic value or a number; this number is called a numeral. Without numbers, we cannot count things. The counting methods have been changing and evolving since the existence of humanity.

In the start, people used to keep some tokens as numbers. For example, the person kept 5 tokens for 5 chickens; if one of his chickens died, he removed one token. In this way, they first used the method of counting.

The methods keep on improving, and people use some symbols to represent different numbers. For example, Egyptians used rope to describe the number 10. The concept kept on developing, and even odd numbers were introduced.

Today, we have mathematical numbers for counting, but Romans used some symbols for counting. These symbols are still used and are very helpful in several cases—for example, Class I, Class IV, etc.

What Are Roman Numerals?

Roman Numerals are the system of numbering used by Romans to denote an integer value. This numbering system uses specific symbols for representing different numbers that are not following the number system of base 10.

Different methods were used for counting at an early age, as discussed earlier. Fingers were also used for counting numbers initially. But counting on fingers was complicated for larger numbers. This led to the idea of representing numbers.

Initially, Romans discovered that there should be some alternative method for counting the numbers. So as a result, a standard system of counting in the commercial and communication sector was introduced by Romans, i.e., Roman Numeral System.

Symbols in Roman Numerals

There are only seven basic symbols that are used to represent thousands of arithmetic numbers. These symbols are the alphabets representing different numbers.

Following is the list of Roman Symbol and respective numbers:

1          I

5          V

10        X

50        L

100     C

500     D

1000   M

Rules To Write Roman Numerals

Some basic rules are followed to write the numbers in Roman Numerals form. You should add the value of the symbol to itself as many times as it repeats itself. For example, III for 3, XXX for 30, and VV for 10.

One symbol can not repeat itself more than three times consecutively. For example, XXX for 30.

You can not repeat the symbols V, L, and D.

In addition, the symbol of a bigger number is written first, followed by the smaller number. For example XI = 10 + 1 = 11

If the smaller symbol is written before, the bigger number symbol, the smaller number will be subtracted from the bigger one. For example, IV = V-I = 5-1 = 4

You can not write symbols V, L, and D before a greater value; hence, they are never subtracted.

You can subtract symbol I only from V and X. the symbol X can only be subtracted from symbols L, M, and C.

Solved Example

Here is a solved example:

Example 1

Convert 1,300 into Roman Numerals.


The calculator will break 1,300 as:

1000 + 100 + 100 + 100

Now, it will write the symbol accordingly as:
