                Addition by ForwArd Counting

                We can use a number strip to add numbers by forward counting.

                Suppose we have to find 5 + 8.

                We start from 5 and count 8 steps forward.
                                              1    2    3    4    5   6    7    8     We reach at 13.

                    0    1   2    3    4    5    6   7    8    9 10 11 12 13 14 15 16 17 18 19 20

                So, 5 + 8 = 13
                Similarly, 9 + 6 = 15
                                                                 1    2    3    4    5   6

                    0    1   2    3    4    5    6   7    8    9 10 11 12 13 14 15 16 17 18 19 20

                            Exercise 3C

                Add by forward counting:

                     0     1   2    3    4    5   6    7    8    9 10 11 12 13 14 15 16 17 18 19 20

                  1.    7  +  7  =                      2.    5  +  9  =                    3.   6  +  9  =

                  4.    6  +  5  =                      5.   4  +  7  =                     6.   9  +  4  =

                  7.    8  +  4  =                      8.   8  +  9  =                     9.   7  +  3  =

                mAking number 10

                Bhiku the monkey is arranging
                bananas in circles. He decides to

                place 10 bananas in a circle.
