SUMMARY

The discussion focuses on the logical negation of conditional statements, specifically the statement "If x is in A, then f(x) is not in B." The correct negation is established as "x is in A and f(x) is in B," represented mathematically as p ∧ ¬q. Participants expressed confusion regarding the transformation of conditional statements into their negated forms, highlighting the need for clarity on logical connectives.

PREREQUISITES
  • Understanding of basic logical connectives (AND, OR, NOT)
  • Familiarity with conditional statements in logic
  • Knowledge of symbolic logic notation (e.g., p, q, ∧, ¬)
  • Basic skills in mathematical reasoning
NEXT STEPS
  • Study the principles of logical connectives in propositional logic
  • Learn about the truth tables for conditional statements and their negations
  • Explore the concept of quantifiers in logic (universal and existential)
  • Practice writing and negating various logical statements
USEFUL FOR

Students of logic, mathematics enthusiasts, and anyone studying formal reasoning or preparing for exams in discrete mathematics.

The Attempt at a Solution


I really didn't know exactly where to go with this, I tried to think what is the logical opposite to any conditional statement. If anyone can point me in the right direction that would be terrific.

Nevermind, I couldn't find anything in the book about the ~(p\Rightarrowq) statements. I finally found that it is equal to p\wedge~q
