Key Concepts in 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.
Trigonometry: Relationships between angles and sides of triangles.
Calculus: Study of change and motion, involving derivatives and integrals.
Statistics: Collection, analysis, interpretation, presentation, and organization of data.
Probability: Study of randomness and uncertainty, quantifying likelihood of events.

Variables: Symbols representing numbers (e.g., x, y).
Equations: Mathematical statements asserting the equality of two expressions.
Functions: Relation where each input has exactly one output (e.g., f(x) = x^2).
Inequalities: Expressions showing the relationship between values (e.g., x > 5).

Points, Lines, and Angles: Basic building blocks of geometry.
Shapes:
- 2D: Circles, triangles, squares, rectangles, polygons.
- 3D: Cubes, spheres, cylinders, cones.
Theorems: Rules such as Pythagorean theorem (a² + b² = c² for right triangles).

Mean: Average value of a set of numbers.
Median: Middle value when numbers are sorted.
Mode: Most frequently occurring value in a dataset.
Standard Deviation: Measure of the amount of variation or dispersion in a set of values.

Experiment: Procedure that yields one of a possible set of outcomes.
Event: A specific outcome or combination of outcomes from an experiment.
Probability Formula: P(Event) = Number of favorable outcomes / Total number of outcomes.

Arithmetic: Fundamental operations include addition, subtraction, multiplication, and division.
Algebra: Uses letters and symbols to express numbers and relationships in equations.
Geometry: Focuses on shapes, sizes, and spatial properties.
Trigonometry: Examines the correlation between angles and sides in triangles.
Calculus: Analyzes change and motion through concepts of derivatives and integrals.
Statistics: Involves data collection and organization, as well as analysis and interpretation.
Probability: Explores uncertainty and quantifies the likelihood of various outcomes.

Variables: Symbols like x and y that denote numbers.
Equations: Mathematical expressions that indicate equality.
Functions: Specific relationships where each input corresponds to one output.
Inequalities: Show comparative values, such as greater than or less than.

Basic Elements: Points, lines, and angles serve as foundational constructs in geometry.
2D Shapes: Includes a range of figures like circles, triangles, and quadrilaterals.
3D Shapes: Comprise solids including cubes, spheres, and cylinders.
Theorems: Include rules such as the Pythagorean theorem relevant to right triangles.

Sine (sin): Represents the ratio of the opposite side to the hypotenuse in a right triangle.
Cosine (cos): Represents the ratio of the adjacent side to the hypotenuse.
Tangent (tan): The ratio of the opposite side to the adjacent side.

Mean: Calculated as the total of values divided by their count, yielding the average.
Median: The middle value in an ordered dataset.
Mode: The most frequently occurring number within a dataset.
Standard Deviation: A measure that indicates the amount of variation in a set of data.

Experiment: A process that produces outcomes from a defined set.
Event: A specific outcome or a combination of outcomes resulting from the experiment.
Probability Formula: Defined as P(Event) = Number of favorable outcomes / Total outcomes.
