Does anyone here know how to do truth tables with logic? Working on some homework and want to verify that I am doing it correctly

it's easier if you go

p q r
t t t
t t f
t f t
t f f
f t t
f t f
f f t
f f f

vary the first every four, the second half that, and the third half of that.

I find it a lot easier on the eyes to use 0 and 1, t/f look too much like each other

Last should be false (bottom-right). Also follow the previous suggestion on style.

Why would that be false?

>> No.6297731

>>6297710
You should first create the truth values for the thing you have in parenthesis. Then compare those values with the p.

It is false because you are having p which is false implying (T or false) which is true. p => (~p v q) in this instance simplifies to F => T which is false always.
