With a conjunction, both statements must be true for the conjunction to be true; but with a disjunction, both statements must be false for the disjunction to be false. Hot Network Questions Is the concept of multiple projects normal in IT industry? This is due, in part, to a lack of opportunities to learn mathematics in early childhood settings or through everyday experiences in the home and in their communities. The sky is blue the sea is green (Conjunction) John will either take Geometry or Algebra (Disjunction) Let P be the statement “John likes to take math classes”, then the negation of P (~P) would be “John doesn’t like to take math classes” Types of Reasoning View gen math week 14.pdf from MATH 001 at Olivarez College. logical negation symbol: The logical negation symbol is used in Boolean algebra to indicate that the truth value of the statement that follows is reversed. ∧ ~ q _ __ b.
