28 350 (total)
Explanation of multiplication by hand, in the above example:
You multiply the 675 by 2 (in 42) = 1350
Move over one place so that the second line would have a blank spot under the "0" in 1350.
Next multiply 675 by 4 (in 42) = 2700
Next you add the two totals, remembering that the 2nd line is moved over one space. So bring down the last zero to the total line. Then, add the next column, 5 plus 0=5 ; 3 plus 0=3; 7 plus 1=8; and bring down the 2. So the answer is 28350 (28,350).
