Proofs! Don't you love em? I hate them, personally. If you don't know what proofs are, they're the damned things you try to prove using truth tables and by symbolic deriviation....

EUGH!

OK, so here's the problems:

write the truth table for (P *exclusive or* Q) or Q
will set as (A) for truth table --^

_P_|_Q_|_(P *exclusive or* Q)_|_A or Q_|
T | T............
T | F............
F | T.............
F | F.............

forgot what exclusive or does... lol

yea, i just realized google would have it. thanks. remembered that, yea, true to either p or q, but not both or neither. owe you guys a :beer:
 
If you need help learning this material send me a PM. I used to grade for a discrete logic class in college and do lots of proofs at work.
 
Doesn't XOR outout true if there are odd numbers of T as inputs and output false if there are even number of T?

Its been over 2.5 years since my last class in logic but I think thats it. Our TA explained it in a thick Russian accent - "Its like man and woman, 2 man or 2 woman (baby) = false, 1 man and 1 woman (baby) = true".
