One possible performance multiplication enhancement is to do a shift and add
instead of an actual multiplication. Since 9* 6, for example, can be written (2* 2
*2 + 1)* 6, we can calculate 9*6 by shifting 6 to the left 3 times and then adding 6
to that result. Show the best way to calculate 13* 5 using shifts and adds/subtracts. Assume both inputs are 8-bit unsigned integers.
