Drop the decimals....we'll go back and add them at the end...so we have

 

   1886

x     87

----------

  13202

15088

----------

164082.  

 

We moved the decimals a total of 3  places to the right in the original problem....so....we need to move them back to the left  a total of 3 places in the answer  = 164.082

 

 

 

cool cool cool
