                  example: Add 36 and 18.
                  Solution: Arrange the numbers one below the other according to the place values

                               of digits. Then add.

                  Step 1.  Add the ones and regroup.                  Step 2.  Add the tens.
                              6 + 8 = 14 ones = 1 ten 4 ones                       1 + 3 + 1 = 5 tens

                              Write 4 in the ones column and                       Write 5 in the tens column.
                              carry over 1 to the tens column.

                                                                                         t    O

                                  t    O                                                 1
                                  1                                                      3    6

                                  3    6                                             +   1    8
                              +   1    8                                                 5    4

                                       4

                  Thus, 36 + 18 = 54

                          Get it right!
