Logical connectives

Logical conjunction

In logic, mathematics and linguistics, And is the truth-functional operator of logical conjunction; the and of a set of operands is true if and only if all of its operands are true. The logical connective that represents this operator is typically written as or â‹… . is true if and only if is true and is true, otherwise it is false. An operand of a conjunction is a conjunct. Beyond logic, the term "conjunction" also refers to similar concepts in other fields: * In natural language, the denotation of expressions such as English "and". * In programming languages, the short-circuit and control structure. * In set theory, intersection. * In lattice theory, logical conjunction (greatest lower bound). * In predicate logic, universal quantification. (Wikipedia).

Learn to show that the converse and inverse are logically equivalent statements

👉 Learn how to show that two statements are logically equivalent. Two statements are said to be logically equivalent if they contain the same logical content. i.e. if both statements convey the same meaning. A conditional statement and its contrapositive are logically equivalent. Also, the

Intro to Logical Statements

We begin our exploration into logic by analyzing LOGICAL STATEMENTS: 1) Define what a logical statement is 2) Recognize examples as logical statements or not logical statements 3) Use the symbols for "not", "and", and "or". 4) Break down a sentence into its logical structure. **********
