                  example 2: Add 382 and 474.
                  Solution:  Write the numbers in place value columns.

                  Step 1: Add the ones.                                   H    t   O
                           2 + 4 = 6 ones
                           Write 6 in the ones column.                    3    8   2

                                                                       + 4     7   4
                                                                                   6

                  Step 2: Add the tens.
                           8 + 7 = 15 tens                                H    t   O

                           Regroup 15 tens into 1 hundred                 1
                           5 tens.                                        3    8   2
                                                                       + 4     7   4
                           Write 5 in the tens column and
                           carry over 1 hundred to the                         5   6

                           hundreds column.

                  Step 3: Add the hundreds.

                           1 (carried over) + 3 + 4 = 8 hundreds          H    t   O
                           Write 8 in the hundreds column.                1    8   2
                                                                          3
                           Thus, 382 + 474 = 856.                      + 4     7   4

                                                                          8    5   6

                  example 3: Add 254 and 168.

                  Solution:   Write the numbers in place value columns.
                                 Step 1: Add the ones.                                                       H    t   O

                                          4 + 8 = 12 ones                                                         1
                                          Regroup 12 ones into 1 ten and 2 ones.                             2    5   4

                                          Write 2 in the ones column and carry over 1 ten to  + 1                 6   8

                                          the tens column.                                                            2
