(3 Points) For the decimal numbers A=17 and B=21, calculate AB using only 6 bits in 2's complement by following the steps below. Clearly indicate your 6-bit result and analyze whether or not it is correct by inspecting overflow. (a) (1 Point) Find 2's complement representations of A and (-B) using 6 bits (b) (1 Point) Do 2's complement addition A+(B), where both numbers are represented with 6 bits 2's complement form. (c) (1 Point) Check overflows and verify your calculation
