-801.
complement form and perform the following operations
(note that the sum is +10,627 and requires five digits and a sign).
(a) (+9,286) + (+801)
(c) (-9,286) + (+801)
(b) (+9,286) + (-801)
(d) (-9,286) + (-801)

1.20 Convert decimal +49 and +29 to binary, using the
representation
and enough digits to accommodate the numbers. Then perform the binary equivalent of
(+29) + (−49), (−29) + (+49), and (−29) + (−49). Convert the answers back to deci-
mal and verify that they are correct.
1.21) If the numbers (+9,742)10 and (+641)10 are in signed-magnitude format, their sum
is (+10,383)10 and requires five digits and a sign. Convert the numbers to signed-10's-
complement form and find the following sums:
(a) (+9,742) + (+641)
(c) (−9,742) + (+641)
(b) (+9,742) + (-641)
(d) (−9,742) + (−641)
1.22 Convert decimal 9,045 and 337 to both BCD and ASCII codes. For ASCII, an even parity
bit is to be appended at the left.
(1.23) Represent the unsigned decimal numbers 609 and 516 in BCD, and then show the steps
necessary to form their sum.
