Key Areas of Mathematics

• Arithmetic focuses on basic operations like addition, subtraction, multiplication, and division. It also delves into properties like commutative, associative, and distributive laws, which govern how these operations interact.
• Algebra is the study of variables and expressions. It uses letters to represent unknown numbers, enabling the manipulation of equations. Equations are statements that express equality between two expressions, providing rules for solving for unknown variables. Linear equations are a common type, while functions represent relationships between sets of numbers, categorized as linear, quadratic, or polynomial based on their structure.
• Geometry explores the properties of shapes, like points, lines, angles, polygons, and circles. It defines theorems, such as the Pythagorean theorem, which establish relationships between sides and angles of triangles. Geometry also involves calculating areas and volumes for both 2D and 3D shapes.
• Trigonometry focuses on analyzing triangles, specifically the relationships between angles and their corresponding side lengths. It introduces trigonometric functions like sine, cosine, and tangent, which are used to solve triangles and understand the relationship between angles and sides. The unit circle is a visual representation that helps understand angles and their corresponding sine and cosine values.
• Calculus is the study of continuous change. It explores concepts like limits, which describe the behavior of functions as they approach specific points. Derivatives measure the rate of change of a quantity, finding applications in tangent lines. Integrals determine the area under curves and accumulate quantities.
• Statistics involves the analysis of data, emphasizing the collection, interpretation, and presentation of information. It focuses on measures of central tendency, like mean, median, and mode, which provide insights into the distribution of data. Probability, which deals with the likelihood of events, is a fundamental concept in statistics.
• Discrete Mathematics explores structures like graphs, sets, and algorithms. It delves into combinatorics, which counts arrangements and combinations, and number theory, which focuses on properties of integers, including prime numbers and divisibility.
