Question

Multiply using partial products

Answer 1

I don't see what we need to multiply but  here is an example: the numbers of the equation that I'm doing is  12 times 13 and this is how I do it .

  (1)(2)                           Step 1: multiply 3 times 2 then when you get the      
x 1 (3)                             answer you would need to multiply then 2 times 3.
  -------                                     
       (36) ( when multiplying 1 times 3 and then multiply 2 times 3)  
     
       
     Step 3: know that in the third step you would need to multiply 1 times 2 then 1 times 1.

    (1)(2)                                    
  x(1) 3
-------------                                        
       36
   + 120  (when multiplying 1 times 2 then 1 times 1 but I added a zero )
-----------
      156 ( I add them all up and that's the answer )
