Perform the arithemetic indicated, maintaining your answer in sign-magnitude
form. Check your result by converting each problem to decimal and repeating the
computation.
a) (1231)4 + (1103)4 = (3000)4
b) (135C)16
+ (1103)16 =
(245F)16
c) (110101)2 – (1011)2 = (101010)2
d) (23)4 X (31)4 = (10033)4
e) (1766)8 – (23)8 = (1743)8
f) (11101101)2 /
(11101)2 =
