Fibonacci Sequence
Fibonacci Sequence
An infinite sequence of numbers starting with 0 and 1, where each subsequent number is the sum of the two preceding ones.
Golden Ratio
Golden Ratio
A special number approximately equal to 1.61803399, often denoted by φ (Phi).
Rational Number
Rational Number
A number that can be expressed as the fraction of two integers; for example, one-half is rational.

Study Notes
Mathematical Language
- Mathematical language uses precise and concise symbols to avoid ambiguity.
- It uses symbols for numbers, letters, binary operations, and special characters.
- Examples of mathematical expressions include: one-half, a number is seven times another number, a number is between -3 and 8, the square of a whole number.
- Mathematical language is precise, concise, and powerful for communicating ideas, avoiding ambiguity.
Fibonacci Sequence
- A Fibonacci sequence is an infinite sequence of natural numbers.
- The first value is 0, the second is 1.
- Subsequent numbers are obtained by adding the previous two numbers in the sequence.
Golden Ratio
- The Golden Ratio (φ) is approximately equal to 1.61803399.
- It's calculated as a/(a+b) = b/a, where 'a' and 'b' are two parts of a whole.
English Language Problems
- English language sometimes lacks precision and conciseness leading to ambiguity.
- These issues are common in mathematical communication.
Mathematical Symbols
- Mathematical symbols used include numbers, letters, binary operations (like addition, subtraction, multiplication), and special characters.
Language of Mathematics
- Provides clear, unambiguous ways to express mathematical concepts.
- Uses concise notation to express complex ideas.
- The language helps to clarify statements, aiding communication.
Importance of Mathematical Language
- Helps to understand expressed mathematical ideas.
- Allows for communication between individuals about mathematical ideas.
Characteristics of Mathematical Language
- Precise: avoids ambiguity.
- Concise: conveys information effectively using few words.
- Powerful: allows to represent/communicate effectively.
Logic
- Used to determine the validity of arguments.
- Propositions are statements that express a complete thought.
Connectives
- Connectives like conjunction (and), disjunction (or), implication (if-then), and biconditional (if and only if) join propositions.
- The rules for interpreting statements involving connectives are important (e.g., "and" means both statements are true, "or" means at least one is true).
Types of Connectives
- Conjunction: (AND) - True only if both sides are true
- Disjunction: (OR) - True if either side or both sides are true
- Implication: (IF-THEN) - False only if the first side is true and the second side is false.
- Biconditional: (IF AND ONLY IF) - True only if both sides have the same truth value.
Truth Value
- Used to describe the truth or falsity of single statements or propositions.
- Can be either true or false.
Truth Table
- Used to depict the truth value of compound statements composed of simpler statements.
- Shows all possible combinations of truth values and their outcomes.
Inductive Reasoning
- Reaches general conclusions based on specific examples.
Deductive Reasoning
- Reaches conclusions by applying general assumptions/procedures.
Types of Reasoning
- Inductive and deductive reasoning are the two main types of reasoning.
Statistics
- The science of collecting, organizing, summarizing, analyzing, and drawing conclusions from data.
- Two major branches include descriptive and inferential statistics.
Variables
- Numerical variables can be ranked or ordered (e.g., age, height).
- Categorical or qualitative variables are non-numerical and can be grouped into categories (e.g., gender, color).
Levels of Measurement
- Nominal: categories without order (e.g., colors)
- Ordinal: categories with order (e.g., rankings)
- Interval: ordered with equal intervals but no true zero (e.g., temperature in Celsius)
- Ratio: ordered with equal intervals and a true zero (e.g., height, weight).
Inferential Statistics
- Used to draw inferences or conclusions about a population from a sample.
