Propositions – This is where letters are assigned to options.

eg. Let (p, q or r) denote (chosen option)

Contrapositive – This is where all the options are turned from positive to negative or vice versa

eg. If p = p, then q =q

Contra =   If not p = not p, then not q = not q

Converse – This is where you swap the two options

eg. If p = q then q = r

Conver = If q = r then p = q
