Arithmetic, Algebra, and Geometry

• Math is the science and study of quantity, structure, space, and change.
• Mathematicians seek out patterns, formulate new conjectures, and establish truth by rigorous deduction from appropriately chosen axioms and definitions.

Arithmetic

• Arithmetic involves the fundamental operations of addition, subtraction, multiplication, and division.
• It deals with numbers and their properties, especially concerning basic operations.
• Fractions, decimals, and percentages are key concepts in arithmetic.
• Understanding order of operations (PEMDAS/BODMAS) is crucial for correct calculations.

Algebra

• Algebra is a generalization of arithmetic, using variables to represent numbers.
• It involves solving equations and inequalities to find unknown values.
• Linear equations, quadratic equations, and systems of equations are common topics.
• Understanding functions and their graphs is essential in algebra.

Geometry

• Geometry deals with shapes, sizes, and relative positions of figures.
• It includes the study of points, lines, angles, surfaces, and solids.
• Euclidean geometry focuses on constructions using a compass and straightedge.
• Concepts like area, volume, perimeter, and circumference are central to geometry.
• Trigonometry, a branch of geometry, examines relationships between angles and sides of triangles.

Calculus

• Calculus focuses on rates of change and accumulation.
• Differential calculus concerns derivatives, which measure instantaneous rates of change.
• Integral calculus involves integrals, which calculate areas under curves and accumulate quantities.
• Limits are foundational to both differential and integral calculus.
• The Fundamental Theorem of Calculus connects differentiation and integration.

Statistics and Probability

• Statistics involves collecting, analyzing, interpreting, and presenting data.
• Descriptive statistics summarize data using measures like mean, median, and mode.
• Inferential statistics uses sample data to make inferences about populations.
• Probability quantifies the likelihood of events occurring.
• Concepts like distributions, hypothesis testing, and confidence intervals are important in statistics.

Discrete Mathematics

• Discrete mathematics deals with objects that can only have distinct, separated values.
• It is essential for computer science and includes topics like logic, set theory, and graph theory.
• Combinatorics involves counting and arranging objects.
• Logic focuses on reasoning and proof techniques.

Number Theory

• Number theory studies the properties of integers.
• Prime numbers, divisibility, and congruences are central concepts.
• Theorems like Fermat's Last Theorem and the Prime Number Theorem are important results in number theory.
• Cryptography relies on number-theoretic concepts.

Mathematical Analysis

• Mathematical analysis is a branch of mathematics that deals with the rigorous study of calculus and related topics.
• It provides a deeper understanding of concepts like limits, continuity, and convergence.
• Real analysis focuses on the properties of real numbers and real-valued functions.
• Complex analysis extends these concepts to complex numbers and complex-valued functions.

Topology

• Topology studies properties that are preserved through continuous deformations, such as stretching, twisting, crumpling, and bending.
• It deals with concepts like connectedness, compactness, and continuity at a more abstract level than calculus.
• Point-set topology is a foundational area that explores properties of topological spaces.
