Calculate the results of each operation. Assume that all numbers are in hexadecimal two's complement representation in an 8-bit container.

For solutions, write "overflow" if overflow occurs, or the hex representation of the solution otherwise (still in an 8-bit container).

a. 4D+F5

b. C0+BE

c. 50+36

d. 1A+E2

e. F6+0F

f.88+13

g. D6+10

h.F9-05

i.FA-8F

j. 99-94

k. 01-86

l. 90-22

m. C1-41

n. 5C-CB

o. DD-BC
