wow its been awhile since i used logic gates...fun 

ok so the expression would be
$$X = (A' OR B)'$$
do they use "v" for or ?

anonymous · Answer

X= NOT(NOT(A) OR B)) 

or 

¬(¬A V B)

dumbcow · Answer

|dw:1397584876933:dw|

anonymous · Answer

it cant be it has to be only 1 line

anonymous · Answer

either its over a and b or just a and or just b or no line at all

dumbcow · Answer

oh i see they simplified it by distributing the negation

~(~A v B)  =  A ^ ~B

the "not" means it has the line over it

anonymous · Answer

so line just over a?

dumbcow · Answer

no the negation is on B, the line would be over B
