firstly, i do apologize for referring to you as a female - i realized your gender once i visited your page. :-).
"⊃" is conditional "only false when antecedent is true and its consequent is false" (if then"
"≡" is biconditional "always having the same truth value" - this is the one i don't quite understand which is another reason i'm having trouble. perhaps both have to either be true or both be false?
