Key Areas in Mathematics

• Arithmetic: Involves basic operations such as addition, subtraction, multiplication, and division, following the order of operations known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
• Algebra: Utilizes variables (symbols for numbers) and constants to form equations, which are statements of equality between two expressions. Functions describe relationships between inputs and outputs, typically denoted as f(x).
• Geometry: Concerns various shapes (triangles, squares, circles) and their properties, including calculations for area, perimeter, and volume. Important theorems include the Pythagorean theorem and principles related to angles.
• Trigonometry: Deals with ratios like sine, cosine, and tangent, and applies these concepts to solve triangles and explore periodic functions. The unit circle, with a radius of one, is essential for defining trigonometric functions.
• Calculus: Focuses on limits (the value a function approaches with variable input), derivatives (how a function changes with input adjustments), and integrals (total accumulation of a quantity over an interval).
• Statistics: Covers data analysis with measures such as mean, median, and mode. Probability explores uncertainty and event likelihood, while distributions include concepts like normal and binomial distributions.
• Discrete Mathematics: Involves combinatorics (counting and arrangement), graph theory (study of graphs and networks), and logic (including propositional and predicate logic).
• Number Theory: Explores prime numbers (natural numbers with no divisors apart from 1 and themselves), divisibility rules for determining factors, and modular arithmetic which focuses on integers and cyclical properties.
• Mathematical Proofs: Encompasses various proof types such as direct, indirect, contradiction, and induction. Proofs validate the truth of mathematical statements.

Fundamental Concepts

• Set Theory: Analyzes collections of objects, emphasizing operations like unions, intersections, and complements.
