Answer:
Explanation:
A contrapositive statement changes "if not p then not q" to "if not q to then, not p." The converse of the conditional statement is “If Q then P.” The contrapositive of the conditional statement is “If not Q then not P.” The inverse of the conditional statement is “If not P then not Q.” if p → q, p → q, then, ∼ q →∼ p ∼ q →∼ p
A Note about Notation: Be careful with the notation a|b
. This does not represent the rational number ab
. The notation a|b
represents a relationship between the integers a
and b
and is simply a shorthand for “ a
divides b
.” "Divides" as in a|b
is a relation (true or false), while "divided by" as in ab
or a/b
is an operation (results in a number).
The definition for “divides” can be written in symbolic form using appropriate quantifiers as follows: A nonzero integer m
divides an integer n
provided that (∃q∈Z)(n=m⋅q).
