In this chapter, you'll learn the answers to questions including:
- How can I use the language of logic to solve math problems?
- What are logical fallacies?
- What are truth tables and values, and how do I use them?
- How can I differentiate between conjunctions and disjunctions?
- What are conditional statements?
- How can I identify the counterexample, contrapositive, converse and inverse of a logical statement?
1. Critical Thinking and Logic in Mathematics
Mathematics involves logic and critical thinking to make connections and draw conclusions. Explore how to use logic, propositions, true or false, and critical thinking in math problems.
2. Logical Fallacies: Hasty Generalization, Circular Reasoning, False Cause & Limited Choice
Logical fallacies refer to ways people attempt to reason and prove statements that are not based on pure fact. Discover four examples of logical fallacies including hasty generalization, circular reasoning, false cause, and limited choice.
3. Logical Fallacies: Appeals to Ignorance, Emotion or Popularity
Logical fallacies are a means of reasoning which are not based on pure facts. Discover three types of logical fallacies and how to avoid them, including appeal to ignorance, appeal to emotion, and appeal to popularity.
4. Propositions, Truth Values and Truth Tables
A proposition is a statement that can be given one of two truth values: it's either true or it is false. Explore how truth values can be placed into a truth table using one of four logic combinations.
5. Logical Math Connectors: Conjunctions and Disjunctions
Logical math connectors are used to combine two statements with either a conjunction or disjunction. Learn how to recognize statements and discover the importance of connectors and the difference between conjunctions and disjunctions.
6. Conditional Statements in Math
A conditional statement is a type of mathematical logic that uses an if-then structure to combine two statements; however, conditional statements may not make sense in reality. Investigate the parts of a conditional statement, and discover how a statement can be true in the world of logic, but false in the real world.
7. Logic Laws: Converse, Inverse, Contrapositive & Counterexample
The validity of a logical statement often can be determined by looking at its logical equivalence. Learn about the logical variants of a conditional statement, and explore the definitions of converse, inverse, contrapositive, and counterexample.
8. Law of Contrapositive in Math: Definition & Example
When a statement is reversed and negated, it is the result of a concept known as contrapositive. Discover how to find the contrapositive of conditional statements.
9. What is a Paragraph Proof? - Definition & Examples
Paragraph Proofs are logical arguments presented in factual statements to determine a specific conclusion in a written paragraph. Using provided examples, learn the steps and outline of effective paragraph proofs.
10. Dominant Strategy in Game Theory: Definition & Examples
In game theory, a dominant strategy is a strategy that gives a player the best outcomes, regardless of the actions of the opponent. Understand the definition of dominant strategy and explore examples of situations demonstrating a dominant strategy.
