Mult. 536 by 410.  Hold the 0 for now and mult your final answer by 10.

Mult 536 by 41:  The first partial product is (536)(1) = 536.
                           The second is (536)(4) = 2144.

Align these partial products as follows:

                          536
                      2144  
                      ----------
                      219760 (we held that final 0, remember?)
