Study Notes
- Mathematics is the abstract science of number, quantity, and space
- It can be studied in its own right (pure mathematics) or as it is applied to other disciplines such as physics and engineering (applied mathematics)
Arithmetic
- Arithmetic is the oldest and most elementary branch of mathematics
- It deals with basic operations on numbers: addition, subtraction, multiplication, and division
- It forms the foundation for more advanced topics like algebra and calculus
- Key concepts include number systems (natural, integer, rational, real, complex), fractions, decimals, percentages, ratios, and proportions
Algebra
- Algebra generalizes arithmetic by using letters or symbols to represent numbers and quantities
- It is used to solve equations and explore relationships between variables
- Key concepts include variables, expressions, equations, inequalities, functions, and graphs
- Different types of algebraic structures exist, such as linear algebra, abstract algebra, and Boolean algebra
Geometry
- Geometry deals with the properties and relations of points, lines, surfaces, and solids
- Euclidean geometry, based on Euclid's axioms, is the standard geometry taught in schools
- Key concepts include points, lines, angles, shapes (triangles, circles, polygons), area, volume, and geometric theorems (e.g., Pythagorean theorem)
- Other types of geometries exist, such as non-Euclidean geometries (spherical, hyperbolic) and differential geometry
Trigonometry
- Trigonometry studies the relationships between the angles and sides of triangles
- It is essential for solving problems involving distances, heights, and angles
- Key concepts include trigonometric functions (sine, cosine, tangent), trigonometric identities, and the unit circle

Calculus
- Calculus deals with the study of continuous change
- It is divided into differential calculus (rates of change and slopes) and integral calculus (accumulation of quantities and areas)
- Key concepts include limits, derivatives, integrals, and functions
- Calculus is used extensively in physics, engineering, economics, and computer science
Statistics and Probability
- Statistics is the science of collecting, analyzing, interpreting, and presenting data
- Probability deals with the likelihood of events occurring
- Key concepts include data types, measures of central tendency (mean, median, mode), measures of dispersion (variance, standard deviation), probability distributions, hypothesis testing, and confidence intervals
- Statistics and probability are used in many fields, including science, business, and government
Discrete Mathematics
- Discrete mathematics deals with mathematical structures that are fundamentally discrete rather than continuous
- It includes topics such as logic, set theory, combinatorics, graph theory, and number theory
- Discrete mathematics is essential for computer science
