      Odd Number

           1.   Numbers which are not divisible by 2 are called odd numbers. 

               Example: 891 is not completely divisible by 2

           2.   Odd numbers are not multiple of 2.

               Example: 1, 3, 5, 7, 9, 11 and so on.

           3.   Odd numbers are not divisible into equal groups without leftovers.

           Example: 455 ÷ 2

           Quotient = 227, Remainder = 1

           4.   Odd numbers have 1, 3, 5, 7, and 9 at their unit place. 

              Example: 2357, 1409, 9981 etc.

           5.   1 is the smallest odd number.

       

      Even Number

               Example: 444 ÷ 2 = 222

           2.   Even numbers are multiple of 2. 

               Example: 2, 4, 6, 8, 10, 12 and so on. 

           3.   Even numbers are divisible into equal groups without leftovers.

           Example: 200 ÷ 2

           Quotient = 100, Remainder = 0

           4.   Even numbers have 0, 2, 4, 6, and 8 at their unit place. 

               Example: 1634, 3710, 8866 etc.

           6.   2 is the smallest even number.

      Addition

       1. Even + Even = Even

         Example: 100 + 100 = 200


       2. Odd + Odd = Even

         Example: 111 + 111 = 222


       3. Odd + Even = Odd

          Example: 101 + 100 = 201

      Multiplication

       1. The product of two even numbers is even. 

           Example: 2 x 4 = 8.


       2. The product of two odd numbers is odd. 

           Example: 3 x 3 = 9.


       3. The product of an even number and an odd number is even. 

           Example: 6 x 3 = 18.
