A = 64 (mod 90) = 64
a) Write the number A as an unsigned 8-bit binary number.
b) Take the negative value of A and find it as a signed 8-bit binary number.
c) Find the values of A + 44 and A + 222 as 8-bit unsigned numbers. Indicate the status of the results (Normal, Inbound, Debt, Overflow).
d) Subtract 18 and 115 from A as 8-bit unsigned numbers. Indicate the status of the results (Normal, Inbound, Debt, Overflow).
e) Add 32, -47, and 121 to A as 8-bit signed numbers. Indicate the status of the results (Normal, Attained, Debt, Overflow).
f) Subtract 22, -77, and 109 from A as 8-bit signed numbers. Indicate the status of the results (Normal, Inbound, Debt, Overflow).
g) Write the BCD equivalent of the number A.
