# General Mathematics Module: Tautologies and Fallacies

This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson.

Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you.

A proposition is defined earlier as a declarative sentence that is either true or false. You also learned that we can combine propositions using logical connectors. Are these compound propositions always true or always false? Think of a sentence that could never be false? How about a sentence that could never be true? To answer these questions, this module will help you identify statements that are always true or always false. This module is written for you to help you understand more, the different logical statements.

The module is composed of only one lesson:

• Lesson 1 – Tautologies and Fallacies

After going through this module, you are expected to:

1. illustrate different types of tautologies and fallacies; and

2. apply tautologies and fallacies to real-life situations.

Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task.
