How to multiply 43 x 92.

            43      x      92
         Code          Double (x2)
             1                92
             2                184
             4                368
             8                736
            16              1472
            32               2944
            64
          128

Since 64 > 43, there is no need to go beyond the 32.
Add code numbers which total 43 :
32 + 8 + 2 + 1 = 43

Now add corresponding numbers in the 92 column :
92 + 184 + 736 + 2944 = 3956

Therefore 43 x 92 = 3956
