                                                                                                  H T O
        Step 2:   Add the tens. 9 + 7 = 16 tens
                                                                                                   1
                     16 tens = 10 tens + 6 tens = 1 hundred + 6 tens                               5 9 1


                      Write  6  under  tens  column  and  carry  over                         + 2 7 4
                     1 hundred to the hundreds column.                                                 6 5






        Step 4:   Add the hundreds.                                                               H T O
                                                                                                   1
                     5 + 2 + 1 (carried over) = 8 hundreds                                         5 9 1

                     Write 8 in hundreds column.                                              + 2 7 4

                     Thus, 591 + 274 = 865                                                         8 6 5





         Add the following.


                  H T O                      H T O                      H T O                      H T O



                   3 4 7                      2 5 6                      4 2 5                      5 2 8

              +        8 4               +        4 5               +        8 6               + 2 8 3






                  H T O                      H T O                      H T O                      H T O



                   2 3 3                      4 3 5                      5 0 7                      2 8 6

              + 6 7 8                    + 2 8 7                    + 3 9 8                    + 3 5 3







         Arrange in columns and add the following.

         (Do these on your notebook.)



         (a) 755 + 61                       (b)  657 + 27                        (c) 888 + 138


         (d) 591 + 274                      (e)  286 + 357                       (f) 182 + 329
