                  Example 1: Sumona has 24 hair clips. She got 5 more. How many hair clips does
                  Sumona have now?

                  Solution: To know the total number of hair clips, we need to add 24 and 5.

                  Step 1. Add the ones first.                            Step 2. Add the tens next.

                               tens Ones                                             tens Ones

                                 2     4                                               2      4

                            +          5                                           +          5
                                       9           +                                   2      9

                  Thus, Sumona has 29 hair clips now.
                  Example 2: Add 50 and 4.                                           Knowledge Desk

                  Solution:                                                        Eleven plus Two is an
