A system that combines arbitrary symbols to produce an infinite number of meaningful staement?
Sounds like you're trying to define Algebra.
What are variables multiplied together to get answers?
Variables are letters representing numbers whose value can be changed depending on the answer. For example: X times 4 = 8 is the problem. X can vary, or become any number you choose. But, in order to make a true statement in this case, X has to equal 2. So, 2 times 4 equals 8, becomes a true staement. You could make X equal 6, but that wouldn't be true. But that's what a variable does; it can change depending on the outcome.
True or false Postulates are accepted as true without proof.?
True
True or false A corollary is a statement that can be easily proved using a theorem?
For Apex the answer is “True“.
How do you construct a truth table for parenthesis not p q parenthesis if and only if p?
Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False
