Fundamental Math Concepts

Arithmetic involves basic operations: addition, subtraction, multiplication, and division. These are foundational for more advanced concepts.
Algebra uses variables and equations to represent and solve unknowns. It manipulates equations and formulas to find variable values.
Geometry studies shapes, sizes, and properties of figures in two and three dimensions, including lines, angles, triangles, circles, and volumes.
Calculus studies change, encompassing differential calculus (rates of change) and integral calculus (accumulation of quantities).
Trigonometry examines relationships between angles and triangle sides using trigonometric functions (sine, cosine, tangent).
Statistics involves collecting, analyzing, and interpreting data using measures of central tendency (mean, median, mode) and dispersion (variance, standard deviation).
Probability quantifies the likelihood of events, using sample spaces, events, and probability calculations.

Arithmetic Operations

Addition combines quantities to find a sum.
Subtraction finds the difference between quantities.
Multiplication repeatedly adds a quantity to get the product.
Division distributes a quantity into equal parts to find the quotient.

Algebraic Equations

Variables represent unknown values, often letters (x, y).
Equations show the equality of two expressions, containing variables and constants.
Solutions to equations are the variable values that satisfy the equation.
Linear equations have a degree of 1 (e.g., y = mx + b).
Quadratic equations have a degree of 2 (e.g., ax² + bx + c = 0).

Geometric Shapes

Lines are one-dimensional figures extending infinitely in both directions.
Angles are formed where two lines or rays meet at a common point, measured in degrees or radians.
Triangles have three sides and three angles; types include equilateral, isosceles, and scalene.
Circles are defined by a fixed center and radius.
Polygons are closed two-dimensional shapes with straight sides.

Calculus Concepts

Derivatives represent instantaneous rates of change.
Integrals represent accumulated quantities.
Limits determine the behavior of a function as its input approaches a specific value.

Trigonometric Identities

Fundamental relationships connect trigonometric functions (sine, cosine, tangent).
Pythagorean identities link trigonometric functions via a relationship similar to the Pythagorean Theorem.
Angle sum and difference identities calculate trigonometric functions of sums or differences of angles.

Statistical Measures

Mean is the average of a data set.
Median is the middle value in a sorted data set.
Mode is the most frequent value in a data set.
Standard deviation measures data spread around the mean.
Variance measures data variability.

Probability Definitions

Sample space lists all possible outcomes.
An event is a subset of the sample space.
Probability measures the likelihood of an event.
Conditional probability is the probability of an event given another event has occurred.
Independent events are events whose occurrences do not affect each other's probabilities.
