As discussed in the text, one possible performance 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 0 × 33 × 0 × 55 using shift s and adds/subtracts. Assume both inputs are 8-bit unsigned integers.
