        Addition by Forward Counting

        We can use this method when we add a 2-digit number with 1-digit number.

        Add 25 and 6.


        Count from 25 and take 6 steps forward. We reach at 31.


             1     2     3    4     5     6
         25 26 27 28 29 30 31 32 33 34                                          So, 25  +  6  =  31
   90   91   92   93   94   95   96   97   98   99   100
