Yes, this is the Russians lately. The following is the method used by the Russian peasants to multiply numbers of any size without needing to know more than the multiplication table for two and half how to calculate a number.
Let's try to multiply 25 by 34.
wrote in a column 25 and 34 in another way:
divide the number on the left by 2 (if we leave decimals, ignore them altogether), and multiply by 2 on the right: 
repeat the process until the column left will be a 1:
Now mark all the numbers that are left and the corresponding pairs in the column on the right: 
Finally add all the numbers in the column to the right that are not crossed out:
The result of multiplying 25 by 34 is actually 850.
The method is valid for any two numbers multiply no matter how many numbers they have.
