Answer 1

do you want an explanation on why it is that answer?

Answer 2

Yes, please. Someone had explained to me before but, I was tired and forgot everything. :(

I'm confused as to where I look in the lines and how I get A, B, A', B', multiplication or addition out of the diagram.

Answer 3

Hmm... I'm not familiar with that symbol (the over/underlined double X). Is it something like a MOSFET?

Answer 4

Hello, stolema. :)

I don't know what a MOSFET is.

Perhaps this PDF from my class could help you help me. (The password is "openstudy" without the quotes.):

What you're referring to is called an X-Gate in the pdf linked above.

@s3a "I'm confused as to where I look in the lines and how I get A, B, A', B', multiplication or addition out of the diagram"

There is no multiplication or addition in your schematic. In boolean logic, the "+" means "logical OR" and the "*" means "logical AND".

Also, the apostrophe means "logical NOT".

Answer 6

Hi, qweqwe123123123123111.

When I said multiplication/addition, I WAS referring to the logical equivalent.

Basically, the trouble I'm having is with converting the diagram into a logical equation. (I remember that I have to somehow follow the lines or something but, I don't remember what I must do, specifically.)
