In mathematics, there are different types of numbers found on the number line such as real numbers, whole numbers, rational and irrational numbers, and many more. Likewise,natural numbers are those numbers that include all positive numbers starting from 1. It basically means that the natural numbers are infinite. These numbers are also regarded as counting numbers as it is only made up of positive numbers rather than negative numbers or zero. Some examples of natural numbers are as follows: 1, 5, 9, 3, 8, etc. They are also considered to be a part of real numbers. The numbers which include every type of number such as integer, fractions, decimals, rational and irrational numbers are defined as real numbers. Some of the examples of real numbers are as follows: -2, 1, – 6/4, etc. In this article, we may cover some basic concepts regarding natural numbers such as a comparison between natural and whole numbers, is 0 a natural number, and many more.
Roman Numbers / Numerals
A system of numbers that was derived from the ancient Greek time which includes latin alphabets can be defined as the Roman Numbers/numerals. It can also be regarded as the type of number which does not exist in place value systems. As the name suggests, the roman numbers were originally first seen in the Roman Empire. It was first used for keeping records and transactions of coins, grains, and many other items. Nowadays, it is difficult to find the roman numbers in use, ut is used in some of the items such as Clocks (the hour mark of the clock), names of Popes in Cathedrals or churches. Some of the examples of these numbers are as follows: I = 1 , V = 5, X = 10, L = 50, C = 100, D = 500 and so on. There are various rules and regulations to be followed while writing these numbers which makes it difficult to understand. Therefore, natural and real numbers are used in place of roman numbers in the modern world.
Can 0 be Regarded as a Natural Number?
As mentioned above, natural numbers are those numbers that include all positive numbers starting from 1. Natural numbers are also known as counting numbers. In our day-to-day life, we do not start counting from 0 as 0, 1, 2, 3 and so on, rather we start counting from 1. Thus, 0 cannot be regarded as a natural number.
Natural Numbers Vs Whole Numbers
The following points mentioned below analysis the points which will help you to distinguish between a natural number and a whole number:
- Whole numbers are those numbers that are not inclusive of numbers like fractions, decimals. Natural numbers are those numbers that include all positive numbers starting from 1. The natural includes numbers like fractions and decimals.
- The whole numbers are denoted by the help of the letter ‘W’. The natural numbers are denoted by the help of the letter, ‘N’.
- The set of whole numbers starts from the number ‘0’ whereas the set of natural numbers starts from the number ‘1’.
- Some of the Examples of Whole numbers are as follows: 0, 1, 3, 6, 7, 8, 9, 10, etc. Some of the examples of natural numbers are as follows: 1, 2, 4, 6, 7, 8, 9, and so on.
History of Roman Numbers
