Question

Given x = -20 and y = -16, use 6-bit two’s complement to compute the followings:

9.a) z = x + y

9.b) z = x - y

9.c) z = -x +y

9.d) z = -x - y

For each case, check for overflow, and convert z to decimal

------------------------------------------------------------------------------------------

First, we need to have the two's complement form of x, y, -x, and -y to simplify our calculation later

(Expecting 6-bits in each of the answer box):

x = -20 = two's complement

y = -16 = two's complement

-x = -(-20) = two's complement

-y = -(-16) = two's complement
