a) I want the answers to the following parts in hex a. What is [A+4]? b. What is [B+4]? c. What is [D+4] 7) Using one byte of storage (8 bits)or 16 bits if needed, what is the binary two’s complement representation of each of the following decimal numbers? a. -111 b. -126
A.a) (A+4)16 = (10+4)10 = (14)10 = (E)16
A.b) (B+4)16 = (11+4)10 = (15)10 = (F)16
A.c) (D+4)16 = (13+7)10 = (20)10 = (14)16
7.a) -111
(111)10 = (01101111)2
one's complement of (01101111)2 = (10010000)2
two's complement form = one's complement form + (1)2 = (10010000)2+(1)2 = (10010001)2
7.b)-126
(126)10 = (01111110)2
one's complement of (01111110)2 = (10000001)2
two's complement form = one's complement form + (1)2 = (10000001)2+(1)2 = (10000010)2
