            Without Regrouping
                                                                                                         H   T   O
            Example : Multiply 312 by 3.
                                                                                                          3   1    2
            Step 1 :  Write the number in columns.
                                                                                                          x         3
            Step 2 :  Multiply 2 one by 3 ones.

                          2 × 3 = 6


                          write 6 under the ones columns.

            Step 3 :  Now, multiply 1 by 3.

                          1 x 3 = 3

                          Write 3 under the tens column

            Step 4 :  Now, multiply 3 by 3.

                          3 x 3 = 9

                          Write 9 below the hundred column.

                          \ 312 × 3 = 936
