Math Problem Statement
) If p→ (p→ q ) is false, then find the truth values of p and q.
Solution
To solve this, we need to analyze the given expression and determine when it is false.
- First, recall the truth table for the implication :
- is false only when is true and is false.
- Otherwise, is true.
Now, we want to be false. This means:
- must be true (since is false only when the antecedent is true and the consequent is false).
- must be false for the entire implication to be false.
For to be false:
- must be true and must be false.
Thus, the truth values are:
Conclusion:
For to be false, must be true and must be false.

- How does double implication (biconditional) differ from implication?
- Can an implication be false when the consequent is true?
- How would you express using logical operators like AND and OR?
- In which logical systems does implication behave differently?
Tip: When analyzing implications, focus on when the antecedent is true and the consequent is false—this is the only time the implication is false!
