Exercise 7. Let x and y be real numbers. (a) Let A be the sentence “If x + y > 0, then x > 0 or y > 0.” Use Theorem 2.10 and one of De Morgan’s laws to show that ¬A is logically equivalent to “x+y > 0 and x ≤ 0 and y ≤ 0.” Be careful not to skip any steps. (Hint: To save writing, feel free to use the abbreviation “≡” for the phrase “is logically equivalent to.” It may help you to review Example 2.3.) (b) Is the sentence A in part (a) true, or is ¬A true? Explain why. (c) Let B be the sentence “If x + y > 2, then x > 2 or y > 2.” Is B true, or is ¬B true, or is it impossible to say without further information about the specific values of x and y? (Hint: Can you find specific values for x and y for which B is true? If so, give an example of such values. Can you find other specific values for x and y for which ¬B is true? If so, give an example of such values.)

Hi, We are learning about Logic and Axiomatic Systems. I have trouble: Identifying which statements are simple statement, and compound statement, and why? And what are the connectives involved if a statement is a compound statement? Here are the given statements: Statement 1: Both players start at the same time. Statement 2: Each player decides which of the seven houses in his control he wishes to begin with. Statement 3: He/she picks up all of the shells from his chosen hole, and moves his hand around the board in a clockwise-direction, dropping one shell in each hole or head he passes over but excluding the opponent's head. Statement 4: If the last shell on the player's hand lands on an empty house, then he/she stops and wait for the next turn. Please help me. Thank you!
