Multiplication 2

           Remember:

           Multiplication works horizontally

           Here is a larger example:

                        x h t u
                        x 2 6 9
                        x   4

First we times 4 by 9 (36) and write down 6 carry 3

                        x h t u
                        x2 6 9
                        x    4
                          x 1 6
                          x ³
Next we times 4 by 6 (24) add the carry (27) and write 7 carry 2

                        x h t u
                        x2 6 9
                        x    4
                          x 7 6
                          x^{2 3}
Finally we times 4 by 2 (8) add the carry and write 10

                        x h t u
                        x2 6 9
                        x    4
                        1 0 7 6
                          x^{2 3}
