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
in math, they act just like parenthesis, to tell you to operate on the terms inside the brackets, first. If you have several levels of nested parenthesis, then using pairs of brackets [] and braces {} help you to see which ones go together. This usually is only used in handwritten problems, as most computer software only recognizes parenthesis () to separate expressions.
Only one space is required before or after a parenthetical statement.
yes
I guess you mean q → p (as in the logic operator: q implies p).To create this truth table, you run over all truth values for q and p (that is whether each statement is True or False) and calculate the value of the operator. You can use True/False, T/F, 1/0, √/X, etc as long as you are consistent for the symbol used for True and the symbol used for False (the first 3 suggestions given are the usual ones used).For implies:if you have a true statement, then it can only imply a true statement to be truebut a negative statement can imply either a true statement or a false one to be truegiving:. q . . p . q→p--------------. 0 . . 0 . . 1 .. 0 . . 1 . . 1 .. 1 . . 0 . . 0 .. 1 . . 1 . . 1 .
You cannot. You cannot ensure the lines are strictly parallel using only a ruler.
Construct a truth table for ~q (p q)
a table like your dinner table where you tell only the truth
The print construct always returns the integer 1, whereas the echo construct has no return value (and as a result, print is slightly slower to execute than echo). Additionally, should you use the parenthesis syntax for both constructs, echo will accept an infinite amount of string arguments whereas print only accepts one.
False
This is not a question.

No, it is not the homo sapiens that can construct their own habitat. Many animals are able to construct their own habitats.
They tend to be known only as parentheses (singular - "parenthesis") or brackets.

Yes.
Only one space is required before or after a parenthetical statement.
