Key Branches of Mathematics

Arithmetic: Basic operations (addition, subtraction, multiplication, division).
Algebra: Use of symbols and letters to represent numbers and quantities in formulas and equations.
Geometry: Study of shapes, sizes, and properties of space. Includes points, lines, surfaces, and solids.
Trigonometry: Focuses on relationships between angles and sides of triangles, including sine, cosine, and tangent functions.
Calculus: Study of change (differential calculus) and accumulation (integral calculus). Key concepts include limits, derivatives, and integrals.
Statistics: Analyzing data to understand variability and trends, including measures of central tendency (mean, median, mode).
Probability: Study of randomness and uncertainty, calculating the likelihood of events.

Numbers:
- Natural numbers (1, 2, 3...), Integers (...,-2, -1, 0, 1, 2...), Rational numbers (fractions), Irrational numbers (non-repeating decimals).
Equations: Statements asserting equality between two expressions; can be linear, quadratic, etc.
Functions: Relationships between sets, typically represented as f(x), mapping inputs to outputs.

Pythagorean Theorem: In a right triangle, a² + b² = c² (where c is the hypotenuse).
Fundamental Theorem of Calculus: Links differentiation and integration, showing they are inverse operations.
Binomial Theorem: Describes the algebraic expansion of powers of a binomial.
