Prof. Hubbard, in question b should the answer been 1001 0000 not 1000 0000. I thought that since both bin numbers 1001 and 1011 both end and begin with 1 that the 1 should stay in an and equation. Also, question e confused me with the answer as well. Should the bin number for q be reversed to 1001 1001 which would make the answer 1001 0001?
Thanks to the anonymous poster above. Here are the corrected answers.
p = 1001 1010
q = 0110 0110
r = 1011 0001
^ means and
v means or
~ means not
