Geometry: Study of shapes, sizes, and properties of figures and spaces.
Trigonometry: Study of relationships between the angles and sides of triangles.
Calculus: Study of change, involving derivatives and integrals.
Statistics: Collection, analysis, interpretation, and presentation of data.

Numbers: Natural, whole, integers, rational, and irrational numbers.
Equations: Expressions set equal to one another; includes linear, quadratic, and polynomial equations.
Functions: A relationship where each input has a single output; includes linear, quadratic, exponential, etc.
Graphs: Visual representations of functions and data; includes plotting points on a coordinate plane.

Addition: Combining numbers to get a sum.
Subtraction: Finding the difference between numbers.
Multiplication: Repeated addition; scaling one number by another.
Division: Splitting a number into equal parts; finding how many times one number is contained in another.

Pythagorean Theorem: In a right triangle, a² + b² = c², where c is the hypotenuse.
Quadratic Formula: x = (-b ± √(b² - 4ac)) / (2a), used to find solutions of quadratic equations.
Fundamental Theorem of Calculus: Links the concept of differentiation and integration.

Understand the problem: Read carefully and identify what is being asked.
Devise a plan: Choose a strategy or method to solve the problem.
Carry out the plan: Execute the chosen method step by step.
Review/extend: Check the solution for accuracy and consider if the solution can be applied to other problems.

Real-world problem solving: Budgeting, finance, engineering, and scientific research.
Data analysis: Used in social sciences, economics, and psychology.
Cryptography: Securing information through mathematical algorithms.

Symbols: Understanding common symbols like + (addition), - (subtraction), × (multiplication), ÷ (division), = (equals), ≠ (not equal).
Sets: Collection of distinct objects, denoted with curly brackets, e.g., A = {1, 2, 3}.

Direct proofs: Show that a statement follows logically from axioms and previously established theorems.
Indirect proofs: Assume the negation of what is to be proven; show this leads to a contradiction.
