Like I said before - I highly recommend sorting the three entered numbers into three variables. Then use the pow(a,b ) function on them however you like.

Sorting three items into decending order...

DeMorgans theorem says:
(x AND y)' = x' OR y'
(x OR y)' = x' AND y'


For your example a:
a. (A + B )' (A' + B')' = 0

This is composed of two expressions ANDed together
Exp1 is (A + B )'

BTW - movlw k copies a LITERAL value k to W - movf f,d copies the CONTENTS of f to d (d=0 - destination is W). That's why movlw OUT1 copies the address of OUT1 instead of it's contents...
