Key Areas of Mathematics

Arithmetic: Involves fundamental operations including addition, subtraction, multiplication, and division.
Properties of Arithmetic: Key properties include commutative (a+b = b+a), associative ((a+b)+c = a+(b+c)), and distributive (a(b+c) = ab + ac).
Order of Operations: Remember PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction) to solve expressions correctly.
Algebra: Uses variables to represent unknown values, allowing for expression formation (combinations of numbers and variables) and equation solving (mathematical statements of equality).
Functions: Establish relationships between sets of inputs (domain) and outputs (range), essential for understanding changes in values.
Geometry: Encompasses basic concepts like points, lines, and planes; studies angles (acute, obtuse, right) and various shapes (triangles, quadrilaterals, circles).
Theorems: Includes significant statements like the Pythagorean theorem (a² + b² = c²) and properties related to similar and congruent figures.
Trigonometry: Focuses on functions such as sine, cosine, and tangent, particularly in right-angled triangles.
Unit Circle: A key concept for understanding angles, radii, and coordinate points.
Applications: Used in modeling periodic phenomena, such as wave functions.
Calculus: Fundamental concepts include limits, which lead to derivatives—representing rates of change—and integrals, which calculate areas under curves and total accumulation.
Fundamental Theorem of Calculus: Connects derivatives and integrals, highlighting their inverse relationship.
Statistics and Probability: Involves data analysis techniques like calculating mean, median, mode, and range to establish central tendencies.
Probability: Evaluates the likelihood of events using various methods, including distributions like normal and binomial.
Hypothesis Testing: Validates claims through statistical analysis, assessing the truth of assumptions.
Discrete Mathematics: Focuses on structures such as graphs and networks in graph theory.
Combinatorics: Explores counting, arrangement, and combination of different objects.
Logic: Examines reasoning processes and argument evaluation.
Algorithms: Outlines step-by-step procedures to solve mathematical computations.
Number Theory: Studies properties of prime numbers, numbers only divisible by 1 and themselves, along with divisibility rules.
Modular Arithmetic: Deals with congruences and arithmetic operations under a fixed modulus.
