While Robert's answer is correct, it will only work for multiplying by numbers that end in 9.  A more general answer is:

One can look at this as (50 + 9) * (50 + 3)

So one has to multiply 50 * 50, 50 * 3, 9 * 50, and 9 * 3, and then add them all together.

So 2500 + 150 + 450 + 27 = 3127

The standard way of doing this is as follows:

                                      5 9

                                  *  5 3

                                 1  7  7      multiply 59 * 3

                          + 2  9  5  0      multiply 59 * 50

                             3  1  2  7      add the two lines above
