Negation

Negation is usually represented with the
sign but we will be using ~. Negation is only used on a single proposition and is the simple process of taking a process. So if A = True then ~A = False. The truth table is as follows:

A~A
T F
F T
As you can see negation is a fairly easy operation. Where this gets tricky is when they ask you for the negations of other equations. So the may ask for negation of A /\ B. So just write out your truth table for A /\ B and then add another column like this:

ABA /\ B~(A /\ B)
TTTF
TFFT
FTFT
FFFT
