• Review and summarize key concepts frequently.
• Work in study groups to discuss and solve problems collaboratively.

Arithmetic

• Core operations include Addition, Subtraction, Multiplication, and Division.
• Follow the order of operations denoted by PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).
• Key properties include Commutative (order does not affect results), Associative (grouping does not affect results), and Distributive (a(b+c) = ab + ac).

Algebra

• Involves variables (symbols representing unknowns) and constants (fixed values).
• Composes Expressions (combinations of variables and constants) and Equations (statements of equality).
• Techniques for solving include linear equations and inequalities, as well as factoring and applying the quadratic formula for quadratic equations.
• Functions represent relationships between quantities using notation; types include linear, quadratic, and polynomial functions.

Geometry

• Fundamental shapes include Triangles, Squares, and Circles, each with distinct characteristics.
• Essential measurements involve Perimeter (boundary length), Area (surface size), and Volume (capacity).
• Important theorems include the Pythagorean theorem for right triangles and properties regarding parallel lines and angles.
• Coordinate geometry analyzes geometrical objects using points, lines, slopes, and employs the distance formula for calculating lengths.

Trigonometry

• Basic trigonometric ratios include Sine (sin), Cosine (cos), and Tangent (tan), vital for angle measures.
• Pythagorean identities relate the squares of these ratios.
• The Unit Circle defines angles in both radians and degrees for a comprehensive understanding of circular functions.
• Right triangle relationships focus on the relationships between angles and side lengths.

Calculus

• Limits explore the behavior of functions as inputs approach certain values, crucial for understanding continuity.
• Derivatives represent the rate of change; rules include power, product, and quotient rules, and applications extend to finding tangents.
• Integrals involve calculating areas under curves (definite integrals) and general growth over intervals (indefinite integrals).
• The fundamental theorem of calculus connects derivatives and integrals, underpinning many applications including volumes of revolution.

Statistics

• Data types are split into Qualitative (descriptive) and Quantitative (numeric).
• Descriptive statistics summarize data using Mean (average), Median (middle value), Mode (most frequent), Range (difference between max and min), Variance (data spread), and Standard Deviation (average distance from the mean).
• Basic Probability principles establish the likelihood of events, differentiating between independent (unrelated) and dependent (affecting each other) events.
• Key distributions include Normal distribution (bell curve) and Binomial distribution (success/failure scenarios).

Mathematical Reasoning

• Differentiates between Inductive reasoning (specific to general) and Deductive reasoning (general to specific).
• Employs proof techniques such as Direct proof (demonstrating truth directly), Proof by contradiction (showing falsehood leads to a contradiction), and Mathematical induction (proving a statement true for all natural numbers).

Mathematical Tools

• Graphing involves the use of a coordinate plane for visualizing functions and relationships.
• Calculators and specialized software aid in performing complex calculations efficiently.
• Mathematical models illustrate real-world applications, helping to solve practical problems using mathematical principles.
