###### Number System:

The number system is a mathematical value that helps count or measure object, length, volume etc. It helps to perform various mathematical calculation such as addition, subtraction, multiplication and division. It also helps in database processing in computer with the help of central processing unit (CPU).

A number system is defined as a system of infinite number with the help of specific digits or symbols. It represents uniqueness  of each and every number. It helps  for arithmetic, algebraic and data processing calculation. In other ways, it helps in engineering like Civil Engineering, Mechanical Engineering etc.

###### There are following types of number system.

We are using Decimal Number System in daily life for calculating the data such Addition, Subtraction, Multiply, Division and Data Processing in computer. We will  discuss the Decimal Number System in details here, further, We will discuss all other Number System in details later.

###### Decimal Number System:-

It contains only 10 digits to form an Infinite Numbers in series. In Decimal Number System, only ten digits i.e. 0,1,2,3,4,5,6,7,8,9,0. A digit’s value in a Decimal Number System depends on its position. Each digits moves from right to left and it is 10 times greater than its previous digit in a Decimal Number System.

###### The number 96758 is written in the expanded form:

It is used extensively in everyday life to carry out routine to take such as buying Groceries, Trading, Mathematics, Computer Science, Physics……etc. The decimal system is also referred as Hindu-Arabic System. It is also used for Addition, Subtraction, Multiplication, Division……

###### The Decimal Number System includes two parts. It consists a decimal point between whole integers and fractional part.

Let an example of Decimal Number System. Which consist decimal point between integer and fraction part. i.e. 3.5

###### Integer part: Number System with Funs and Facts

Here integer part is 3 before the decimal point. Its value depends on the position in decimal number before the decimal point.

###### Fraction part: Number System with Funs and Facts

Here fraction part is 68 after the decimal point. Its value also depends on the position in decimal number after the decimal point. It means 0.68, it is always smaller than 1. Hence, 0.68=(6/10)+(8/100)

Let an example of Decimal Number System. Which consist decimal point between integer part and fraction part. i.e. 45.68

Fractional part is also written in this form also: 0.5=1/2; 0.75=3/4

###### Scientific Notation of Decimal Number System

Scientific Notation is a short form of either a very large number or a very small number in the multiplication form. It is easy to write in this form and save the time and a piece of paper. It is very difficult to represent the actual form of a large decimal number. Hence we use scientific notation. The general representation of scientific notation is: y x 10z ; where 1≤y≤10
