Astra AI’s video library helps students learn mathematics at their own pace. - [Algebra](https://astra-ai.co/videos/algebra.md): Algebra is the study of expressions, equations, and the rules for manipulating them. This topic walks through the core ideas used across school mathematics. - [Arithmetic](https://astra-ai.co/videos/arithmetic.md): Arithmetic covers the basic operations on numbers: addition, subtraction, multiplication, and division. This topic reviews the rules students use every day. - [Combinatorics](https://astra-ai.co/videos/combinatorics.md): Combinatorics is the mathematics of counting. This topic covers permutations, combinations, and the basic counting principles. - [Complex Numbers](https://astra-ai.co/videos/complex-numbers.md): Complex numbers extend the real numbers with the imaginary unit. This topic covers their form, the complex plane, and basic operations. - [Derivatives](https://astra-ai.co/videos/derivatives.md): Derivatives measure how a function changes. This topic covers the definition, derivative rules, and tangent lines. - [Division](https://astra-ai.co/videos/division.md): Division splits a quantity into equal parts. This topic covers division facts, remainders, and how division connects to multiplication. - [Financial Mathematics](https://astra-ai.co/videos/financial-mathematics.md): Financial mathematics applies percentages and interest to real money problems. This topic covers simple and compound interest and related calculations. - [Functions](https://astra-ai.co/videos/functions.md): Functions pair each input with exactly one output. This topic covers function notation, domain and range, and graphs. - [Integrals](https://astra-ai.co/videos/integrals.md): Integrals measure accumulated change and the area under a curve. This topic covers antiderivatives, definite integrals, and the main rules used in calculus. - [Limits](https://astra-ai.co/videos/limits.md): Limits describe the value a function approaches as its input approaches a point. This topic introduces limit rules and continuity. - [Logarithms](https://astra-ai.co/videos/logarithms.md): Logarithms are the inverse of exponential functions. This topic covers log rules and how to solve exponential equations. - [Natural and Whole Numbers (Integers)](https://astra-ai.co/videos/natural-and-whole-numbers-integers.md): Natural and whole numbers, including integers, are the counting numbers and their negatives. This topic covers the number line and basic properties. - [Plane Geometry](https://astra-ai.co/videos/plane-geometry.md): Plane geometry studies shapes in two dimensions. This topic covers points, lines, angles, triangles, and circles. - [Polynomials](https://astra-ai.co/videos/polynomials.md): Polynomials are algebraic expressions made of terms with coefficients and a variable raised to an integer power. This topic covers their structure, basic operations, and uses in algebra. - [Rational Function](https://astra-ai.co/videos/rational-function.md): A rational function is a quotient of two polynomials. This topic covers domains, asymptotes, and how these functions behave. - [Rational Numbers](https://astra-ai.co/videos/rational-numbers.md): Rational numbers are numbers that can be written as a fraction of two integers. This topic covers fractions, decimals, and how to compare them. - [Real Numbers](https://astra-ai.co/videos/real-numbers.md): Real numbers include rationals and irrationals on the number line. This topic explains the sets of numbers and how they fit together. - [Sequences](https://astra-ai.co/videos/sequences.md): Sequences are ordered lists of numbers. This topic covers arithmetic and geometric sequences and how their terms are built. - [Trigonometry](https://astra-ai.co/videos/trigonometry.md): Trigonometry relates angles and side lengths in triangles. This topic covers sine, cosine, tangent, and the unit circle. - [Vectors](https://astra-ai.co/videos/vectors.md): Vectors have both magnitude and direction. This topic covers components, addition, and how vectors are used in geometry.
