What does the statement p arrow q mean?

It means the statement P implies Q.


What is the contrapositive of the contrapositive?

Given two propositions, p and q, start out with p implies q. For example if a number is even it is a multiple of 2. So we are saying even implies multiple of 2. Now the contrapositive is not p implies not q so if a number is not even it is not a multiple of 2. Or if not p then not q. The contrapositive of the contrapositive would negate a negation so that would make it positive. If not (not p) then not(not q) or in other words, you are back where you started, p implies q.


What is a syloogism?

sylogism is a law of geometry that states that ifp implies q and q implies r then p implies rhope this is what you were looking for :-)


What is the law of modus tollens?

It in Math, (Geometry) If p implies q is a true conditional statement and not q is true, then not p is true.


Prove that if a and b are rational numbers then a multiplied by b is a rational number?

If a is rational then there exist integers p and q such that a = p/q where q>0. Similarly, b = r/s for some integers r and s (s>0) Then a*b = p/q * r/s = (p*r)/(q*s) Now, since p, q r and s are integers, p*r and q*s are integers. Also, q and s > 0 means that q*s > 0 Thus a*b can be expressed as x/y where p and r are integers implies that x = p*r is an integer q and s are positive integers implies that y = q*s is a positive integer. That is, a*b is rational.

What is is called when a conditional and its converse are true and they are written as a single true statement?

It is an if and only if (often shortened to iff) is usually written as p <=> q. This is also known as Equivalence. If you have a conditional p => q and it's converse q => p we can then connect them with an & we have: p => q & q => p. So, in essence, Equivalence is just a shortened version of p => q & q => p .


What is the sum or difference of p and q?

The sum of p and q means (p+q). The difference of p and q means (p-q).


What is the truth table for p arrow q?

Not sure I can do a table here but: P True, Q True then P -> Q True P True, Q False then P -> Q False P False, Q True then P -> Q True P False, Q False then P -> Q True It is the same as not(P) OR Q
