Hi Symmeatra,

Different texts and courses use different kinds of symbols for propositional logic, but I'll get you started on a few these. Once you have that, you should be able to figure out the rest:

1) Could be symbolized as just ABC, A * B * C or similar. We are basically multiplying the truth value of each proposition.

2) Just place a !, ~ or whatever not symbol you are using in front of the answer to (1). This negates the truth value from (1)

5) (A | B | C) -> (ABC). This means that "If A or B or C is true, then all three are true."

You can probably get the rest from there. :)
