Learn Number System

Today we are going to learn about Number systems which is a part of cbse syllabus,
and learning Number systems can be useful for your Homework help.
Number system is said to be as the set of numbers on which one or more operations are performed like addition or multiplication.
Number system consists of real numbers, natural numbers,rational number and complex numbers to name  a few.
Number system is a way of counting  things. it is a way of identifying the quantity of something.
The most commonaly used system of numerals is the hindu- Arabic numerals.
Number system consists of natural numbers:
Natural numbers consists of set of all whole numbers greater than zero.

We are now going to discuss about the types of numbers
1.     Natural numbers
2.     Whole numbers
3.     Integers

Natural numbers: Numbers are classified according to type. The first type of number is the "natural" numbers:
Eg 1,2,3,4,5  (Learn more about natural numbers here),
The next type is the "whole" numbers, which are the natural numbers together with zero
For example we can say that 0,1,2,3,4,5
Prime numbers:
Prime numbers are the numbers which are only divisible by one or itself
Like 2,3,4,5,
Odd numbers : odd numbers are the numbers which are not the multiples of two like 3,5,7 etc they always end with the numbers like 1,3,5,7,9,11
Now we explain other types of numbers like
Even numbers: these numbers always end with numbers,0,2,4,6 or 8
Now we learn about the other number like
Rational numbers: a ational number is a number which can be expresses as a ratio of two integers.non –integer rational numbers are usually written in the form of a/b an b is not equal to zero.
Irrational numbers: these are the numbers which are not rational
We can take the examples like 3.14
Real numbers: these are those numbers which are made up of both rational and irrational numbers.
Imaginary numbers: The imaginary numbers are the numbers are the numbers based on the imaginary number i
Now we have a brief idea about the numbers and the types of numbers
Number system is also the most important part of grade V mathematics .
Number system and the type of numbers are set of operations related to addition and multiplication
Numeral system is also known as the numeral system.
We can further explain the grade V mathematics related to Number system and the types of numbers as follows.
The  most commonly used system of numerals is known as Arabic numeral or hindu-arabic numeral.
A number system is the set of symbols used to express quantities as the basis for counting, determining order, comparing amounts, performing calculations, and representing value. It is the set of characters and mathematical rules that are used to represent a number.

Thus we can now sum up and say that the number system,The types of numbers are the basis of maths and is important for understanding and solving various topics related to mathematics.
So now we have the full knowledge of the number system, types of number system and the above information will  help the students of grade V
in understanding the basic number system and If anyone wants to know about Steps in problem solving then they can refer Internet and text books.
