About the XOR function, I think I got a little confused about the 1s and 0s... originally when I looked at the truth table it was in binary, so I converted it over to T and F... mixed up my Ts and Fs... so it should be that XOR is true if and only if one of its operands is true except when both are true, then it's false... I have class now but I'll get that changed right away. Sorry for the mistake and thanks for letting us know.
