Does anyone know what website to visit to help me with Truth Tables? Im having a hard time understanding some logics about it. :)

OMG I learned about this today!


Here's what I know. Let's take 2 letters, "p" and "q."

Make a chart that is almost like an elongated T chart. Put p and q on the left but don't put a line between them.

Under p you put the following letters in the exact order you see. T = true, F = false


p q
T T
T F
F T
F F


If there is a "~" next to either letter, that is a negation of that letter. In other words, "~p" means "not p." It means q instead.

Other symbols that would help

p ^ q (it should be an upside down V but a carat is the only one that comes close) means "p and q"

p V q means "p or q"

^ = Everything is false unless both statements are true
V = Everything is true unless both statements are false

So take that p and q table I made. If p ^ q applied to it

p q
T T = T
T F = F
F T = F
F F = F

If p V q applied to it


p q
T T = T
T F = T
F T = T
F F = F

Here's an example from my notes. P = false q = true
~ p ^ (p V q)
~F ^ (F V T)
T ^ T
T

Another thing that might be useful:

~ (p V q) = ~p ^ ~q


Does that help a little?

What the hell are truth tables?

It's a math thing. It's hard to describe what it's supposed to do.

What the hell are truth tables?Truth tables are used in solving logic. Are you guys learning this in math class or for a computer class? I'm in computer science major... and I get a lot of these stuff. They drive me nutso. LOL :crazy:

I learned it in an Exploring Mathematics class.

yes it does! thanks Brian! :D

Ohhhh its MATH.
I failed Math in highschool.Hated it with a passion.

Math is fun, I love it. :eek:

oh god, im thankful i have no idea what you guys are talking about. i hate math with a passion.

shoot, thats how i felt earlier today when the teacher was explaining the stuff! :lol:

oh god, im thankful i have no idea what you guys are talking about. i hate math with a passion.
:yeahthat

What the hell are truth tables?
I never heard of them either :lol:

:lol: we just started a chapter about all that in geometry.

p => q
q => p
not-p => not-q
not-q => not-p.

What the hell are truth tables?Thats what im trying to figure out!!
