Study Notes
Mathematical Logic
- Propositions: Statements that are either true or false (but not both).
- Propositional variables: Symbols like 'p', 'q', 'r' used to represent propositions.
-
Logical connectives: Combine simple propositions to form compound statements.
-
Negation:
¬p, meaning "not p". The truth value is opposite of 'p'. -
Conjunction:
p ∧ q, meaning "p and q". True only when both 'p' and 'q' are true. -
Disjunction:
p ∨ q, meaning "p or q". True unless both 'p' and 'q' are false. -
Conditional/Implication:
p → q, meaning "If p, then q". False only when 'p' is true, and 'q' is false. -
Biconditional/Double Implication:
p ↔ q, meaning "p if and only if q". True when both 'p' and 'q' have the same truth value.
-
Negation:
-
Conditional Proposition: Implies a relationship between an antecedent (hypothesis) and a consequent (conclusion).
- Inverse: Negates both the antecedent and consequent.
- Converse: Swaps the antecedent and consequent.
- Contrapositive: Forms the inverse of the converse.
Problem Solving
- Problem: A question requiring a solution, typically involving mathematical operations.
- Problem-Solving: A process using skills to identify and implement solutions.
- Simple Equation: Solution is a combination of method (techniques) and answer.
-
George Pólya: Considered "the Father of Problem Solving", his framework includes:
- Understand The Problem: Grasping the underlying concepts, terminology, and principles.
- Devise a Plan: Utilize various strategies (heuristic methods) to solve the problem.
- Carry Out the Plan: Implement the chosen plan. Be prepared to adjust if the initial plan proves ineffective.
- Look Back: Verify the solution by checking if the conditions are satisfied.
Reasoning in Mathematics
- Inductive Reasoning: Moves from specific observations or examples to a general conclusion.
- Deductive Reasoning: Begins with a general statement (hypothesis) to reach a specific conclusion using logic.
Consumer Mathematics
- Hourly Pay: Amount paid per hour worked.
- Straight-Time Pay: Hourly rate x hours worked.
- Overtime Pay: Compensation for work exceeding 8 hours/day or 40 hours/week.
- Salary: Fixed income, paid regardless of hours worked.
- Commissions: Additional earnings for selling goods or services.
- Interest: Money earned when money is invested.
- Simple Interest: Calculated on the principal (original) loan amount.
