P(x) = axp +  ...  +  bxq
Q(x) = cxr +  ...  +  dxs

Russian Peasant Multiplication

This method involves a process of halving and doubling, which reduces one factor to powers of two and uses the distributive property of multiplication over addition to calculate a product.

Multiplication

                              25                    37
                              12                    74
                              6                      148
                              3                      296
                              1                      592
                            -------------------------           Therefore, 37 + 296 + 592 = 925
                                                      925                              ( 25 x 37 = 925 )
