                  Step 1.   Multiply the ones and regroup.              Step 2. Multiply the tens and add the

                    7 × 5 = 35 ones                      H    t   O     carried over.                         H    t   O

                             = 3 tens + 5 ones                3         6 × 5 = 30 tens                       3    3

                  Write 5 in the ones column                  6   7     30 tens + 3 tens = 33 tens                 6   7
                                                     ×            5                                       ×            5
                  and carry over 3 to the                               = 3 hundreds + 3 tens
                                                                  5                                           3    3   5
                  tens column.                                          Write 3 in the tens column

                                                                        and 3 in the hundreds column.
                  Thus, 67 × 5 = 335.
