Whole Numbers

All natural numbers together with zero form the collection of all whole numbers. It is denoted by "W"
W = { 0,1,2,3,4,5,6,7,8,9,10, ............... }

Type of Whole Numbers

1. Even Numbers
2. Odd  Numbers

1. Even Numbers

A number which is divisible by 2, it is called even number. It is denoted by "E". 
E = { 0,2,4,6,8,10,12,14,16,18,20,  ........ }

2. Odd Numbers

A number which is not divisible by 2, it is called odd number. It is denoted by "O".
O = { 1,3,5,7,9,11,13,,15,17,19,21, ....... }

Decimal Number Decimal numbers are numbers that are written according to their place value. The decimal point is used to separate whole part from number value less than one.A symbol is used " . ", this is called decimal point. Example: 65.894 where 65 is a whole part and 894 is a fractional part. Type of Decimals 1. Terminating Decimals  2. Non-terminating Decimals 1. Terminating Decimals Every fraction a/b can be expressed as a decimal. If the decimal expression of a/b terminates i.e. comes to end, then the decimal so obtained is called a terminating decimal. Example: 1/2 = 0.5                   5/4 = 1.25                 13/5= 2.6 Thus, each of the numbers 1/2, 5/4 and 13/5 can be expressed in the form of a terminating decimal. 2. Non-terminating Decimals While expressing a fraction in the form of decimal, when we perform division we get some remainder. If ...
