An oldest Russian Method of Multiplication

÷2 |  x2
     |
67 x  38
     |
33 |  76
16 |  162 -->ignore 162 (16 is even)
8   |  324 -->ignore 324 (8 is even)
4   |  648 -->ignore 648 (4 is even)
2   |  1296 -->ignore 1296 (16 is even)
1   |  2084
---------------
         2598  ( sum of 38,76,2598 )
---------------

* Devide 67 by 2, by ignoring remainders and take dividend.
* Multiply 38 by 2 and take the multiplicand.
* Ignore Multiplicands where even dividend occurs.

Hence 67 x 38 = 2598

* This method of multiplication can be given as an exercise to VI MATHS students.
