Every idea starts as a picture or interactive model, then becomes notation.
Mathematics · Intermediate
Algebra & Functions, Visually
Functions are the grammar of science and computing. Here every equation comes with a picture you can drag, stretch and question — so the symbols finally mean something.

What you'll be able to do
- Read any graph as a story of change
- Move fluently between table, graph and formula
- Model growth and decay with exponentials
- Build intuition for rate of change before calculus
Module by module
01Functions as machines
Input, rule, output — and why that idea is everywhere.
02Linear change
Slope as rate; lines as the simplest model of the world.
03Systems of equations
Where two constraints meet, visually and algebraically.
04Quadratics and parabolas
Completing the square as a geometric rearrangement.
05Transformations
Shift, stretch and reflect any graph by reasoning, not rules.
06Exponential growth
Doubling, compounding and why intuition fails at scale.
07Logarithms
The inverse question: how many steps to get there?
08Sequences and series
Arithmetic and geometric sums, proved visually.
09Towards calculus
Average vs instantaneous rate of change.
The WyPy way
Reason it through
Guided problems ask you to think and explain, not to copy a method.
Step by step
Short lessons with checkpoints, so each idea is solid before the next.
Who this course is for
Designed for
High-school students, and anyone who wants functions and graphs to make sense before calculus.
