Overview: |
This informational material will introduce negations and explain how to represent these logical statements with symbols in truth tables. It will introduce the term tautology and explain how a truth table can demonstrate a tautology. Practice questions with a PDF answer key are provided. In addition, there is a self-checking online practice tool. |
