Addition with Regrouping/Carrying


        We have learned the concept of tens and ones. Let us learn how to regroup

        and add.


        Let us add 16 and 18.




                T  O

                                           1 ten
                1      6

                                       6 ones
                                                                                   14 ones

             +  1      8                    1 ten


                                          8 ones                                1 ten

                3      4        4 ones                                   4 ones






                               3 tens






        Let us learn how to carry over and add.



                                          Step 1:    Add ones.

                     T  O

         Step 2        1                               (6 + 8 = 14 ones = 1 ten + 4 ones)
                     1       6            Step 2:  We write 4 in the ones column and carry


                   +  1      8                         1 to tens column.


                     3     1  4           Step 3:   Now, we add the tens column, we get




                                                       1 + 1 + 1 = 3
                   Step 3  Step 1
                                                       So, 16 + 18 = 34





                                                                                                              89
   86   87   88   89   90   91   92   93   94   95   96
