What is a natural number?

The natural number, which can also be called counting, is represented by numbers from 1, 2, 3 until infinity. Number 0 is included if natural numbers are defined as negative integers, but not if they are defined only as positive integers. There must be an endless number of natural numbers in mathematics, because each natural number is partially defined by having the number that follows it. These numbers are also integers, not fractions or decimal places, and can be used for counting or ordering. There is no number below zero and the natural number cannot follow zero, as is the case of -1.0. Basically, it defines natural numbers like anything zero or higher, which is all and not fraction. Zero is generally considered the only natural number that is not positive.

The zero concept has long developed after the number of numbers began to use. The oldest records counting numbers from 1-10 to over 4000 years when the Babylonians used the use of a particularwritten code to indicate a place. The Egyptians wrote hieroglyphs for each digit, but only about 1000 BC was the concept of zero created by the Mayan and Olmec civilizations.

Although OLMEC and Mayan groups show the first records of zero use, the concept of zero has also evolved in India, in the 7th century BC. It was Indian use, rather than a meso -American use that has accepted civilization as Greeks.

There are many ways to use natural numbers in mathematical applications. They can reduce problems by indicating that the answer must be a natural number. They are also studied in a specific application in the theory of a set, mathematics that evaluate sets of things. Numbers theory can evaluate natural numbers as part of a set of integers or independently to see if they behave in a certain way or show certain properties.

maybe one of the widest uses of naturalThe numbers come very "naturally". When we are young, we will learn to count from 0 further. Even young children can easily start learning the difference between one and two, or explain how old they are. This study continues when children start school and learn to manipulate natural numbers, how to multiply, divide, add and subtract them. Only after learning the concept of natural numbers, is the concept of established integers and the possibility of negative numbers that may first confuse some children, will usually learn the first in the fourth or fifth grade.
