                        b.

                                                        +                             =

                        c.

                                                         +                             =

                Adding Zero (0)

                   There is no bird            4 birds come  to  sit  on             How many  birds  are

                   on the tree.                the tree.                             there on the tree now?
                                                                                     Clearly, 4.

                                                                                     So, 0 + 4 = 4.

                                                                                     Similarly, 4 + 0 = 4

                When we add  any number to  zero or zero to  any number, we get  the
                same number.

                Adding one (1)

                 There are four birds  One more  bird comes  How many birds are there
                 on a tree.                      to sit on the tree.                on the tree now?

                                                                                    Clearly, 5.

                                                                                    So, 4 + 1 = 5
                                                                                    Also, 1 + 4 = 5

                Thus, there are 5 birds on the tree now.
                When we add 1 to a number or a number to 1, we get the number that

                comes just after that number.
