Early Math: Counting & Addition
A friendly first course in numbers — counting, comparing, and adding small amounts with hands-on examples.
Multiplication & Division
Times tables that make sense: equal groups, arrays, and sharing fairly — the foundation for all later math.
Telling Time & Money
Read a clock and count coins with confidence: hours and minutes, dollars and cents, and making change.
Fractions & Decimals
Parts of a whole made friendly: naming fractions, comparing them, and meeting decimals for the first time.
Pre-Algebra Foundations
Bridge arithmetic and algebra: integers, fractions, ratios, and the meaning of a variable.
Algebra I
Linear equations, inequalities, and functions — the core algebra every high schooler needs.
Mental Math Tricks
Fast, friendly tricks for adding, doubling, and multiplying in your head — no paper needed.
Geometry
Reason about shape and space: angles, triangles, the Pythagorean theorem, and proof.
Algebra II
Quadratics, exponents, logarithms, and functions — the algebra that opens the door to calculus.
Statistics
Make sense of data: mean, median, and mode, plus the basics of probability and chance.
Trigonometry
Sine, cosine, and tangent from triangles to the unit circle — the math of angles, waves, and rotation.
Calculus I
Limits, derivatives, and integrals — the mathematics of change, with worked intuition.
Probability & Combinatorics
Counting, chance, and combinations — from coin flips to how many ways a team can line up.
Precalculus
Bridge algebra and calculus: functions, domain and range, and an introduction to trigonometry.
Linear Algebra
Vectors, matrices, and linear transformations — the backbone of data science and graphics.
Discrete Mathematics
The math of computer science: logic, proofs, sets, counting, and graphs — reasoning about discrete structures.
Differential Equations
Equations whose unknowns are functions: model growth, decay, and oscillation, and see why solutions behave as they do.
Numerical Methods
How computers solve equations they can't solve exactly — roots, integrals, and error.
Number Theory
Primes, divisibility, and modular arithmetic — ancient questions about whole numbers that now secure the internet.
Real Analysis
The rigorous foundation of calculus: sequences, limits, and epsilon-delta proof.
Algebraic Topology
Doctoral study of shape up to deformation: homotopy, the fundamental group, and homology.
