                  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
                  and carry over 3 to the            ×            5    = 3 hundreds + 3 tens              ×            5

                  tens column.                                    5    Write 3 in the tens column             3    3   5

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