Study Notes
Mathematical Language and Symbols
- Mathematics serves as the universal language across various fields including sciences, economics, music, architecture, and politics.
- Mathematical language encompasses numbers, symbols, sets, operations, functions, equations, abstraction, logic, coding, and decoding.
- Symbols in mathematics are primarily understood by those with formal training in the subject matter.
Characteristics of Mathematical Language
- Precision: Mathematics allows for fine distinctions and definitive expressions.
- Conciseness: It conveys ideas succinctly compared to longer verbal or written explanations.
- Power: Complex thoughts can be expressed simply and effectively.
Expression vs. Sentence
- An expression is analogous to an English noun, representing a mathematical object through a correct arrangement of symbols.
- A mathematical sentence reflects an English sentence, conveying a complete thought, e.g., "The sum of any two real numbers is also a real number."
Elementary Logic
- Logic studies truth based on the meanings of terms and is fundamental for reasoning and forming opinions.
- Mathematical Logic: A structured method that helps determine the validity of arguments through established rules and techniques.
Propositions
- A proposition is a declarative sentence that is either true or false, not both.
- Examples of propositions:
- True: "The sum of 3 and 8 is 11."
- False: "9 is a prime number" (as it is divisible by 3).
- Non-propositions include interrogative sentences and incomplete thoughts, which cannot be judged as true or false.
Compound Statements
- Formed by combining two or more propositional statements using logical connectives:
- Conjunction (AND): Both statements must be true, e.g., "√2 is rational AND 6 is even."
- Disjunction (OR): At least one statement must be true, e.g., "√2 is rational OR 6 is even."
- Negation: Opposite of a proposition, e.g., "√2 is NOT a rational number."
- Implication (If... then...): A conditional statement indicating that if the first part is true, the second must follow, e.g., "If √2 is rational, then 6 is even."
- Biconditional: A statement claiming both conditions are true together, e.g., "√2 is rational IF AND ONLY IF 6 is even."
Truth Tables for Compound Statements
- Truth Tables: Tools to display the truth value of compound statements based on the truth values of their individual components.
- They clearly outline the possible outcomes for conjunctions, disjunctions, negations, implications, and biconditional statements.
