When we have a statement and we want to prove the converse, contradiction, and contrapositive. When we prove the contrapositive we know that its logically equivalent to the original statement so no further steps are needed, but what kind of extra steps do we need to prove the converse and contradiction? Maybe using the following statement could assist in the explanation?: "Let n ∈ Z. Prove that (n + 1)2 − 1 is even if and only if n is even.

5. Write the following statements symbolically and then demonstrate whether they are true or false. If true, then prove it, If false, then provide a counterexample or prove that the negation of the statement is true. (a) For all integers, if 9 divides n2, then 9 divides n. (b) There exist integers m and n such that 15m + 12n = -6.

Decide which of the following are true statements. Provide ashort justification for those that are valid and a counterexample for those thatare not: (a) Two real numbers satisfy a < b if and only if a < b + epsilon for every epsilon > 0.(b) Two real numbers satisfy a < b if a < b + epsilon for every epsilon > 0.(c) Two real numbers satisfy a ≤ b if and only if a < b + epsilon for every epsilon > 0.
Decide whether or not the following propositions are true or false. Justify each ofyour conclusions with a proof or a counterexample.(a) ∃x ∈ R (x 2 = x 3 and x > 0)(b) ∀n ∈ N + (2 n + 3 is prime)(c) ¬∃x ∈ R (x 2 < 36)
1 Quantifiers Consider the domain of integer numbers, and let P(x) be the statement x < x³. For each of the following formulas determine their truth values. You must justify your answers. Simply stating true or false will give you no credit, even if your answer is correct. а) Р(2) b) Р(-1) c) VxP(x) d) 3xP(x) e) 3!xP(x)

Let S be the statement: For all r, y E R, if x + y = 0 then xy < 0. (b) Decide whether the statement S is true or false, giving a proof or counterexample as appropriate. (c) Write down the statement obtained by replacing the implication in S by its converse. Decide whether this new statement is true or false, giving a proof or counterexample as appropriate. (d) Write down the statement obtained by replacing the implication in S by its contrapositive. Decide whether this new statement is true or false, giving a proof or counterexample as appropriate.
Please if able give an example for both propositions showing how they satisfy the given points, especially proposition 2 is the one I struggle with.
Evaluate the proposition ∀∃y.P(x,y) ⇐⇒ ∃y.∀x.P(x,y) for an unknown predicate P. Could the statement be true? Must the statement be true for all P? Give a specific P (with domains for x and y) where it is either true or false. Prove that it is true for all P, or show a contradiction.
Disprove the following statement. Then write the negation of the following statement, and prove that the negation of the statement is true. Vintegers m and n, if 2m + n is odd then m and n are both odd.
