THE MAP_

All of mathematics as one dependency tree — 69 nodes from counting to the spectral theorem. Master the prerequisites, unlock the frontier, climb.

BEDROCKNumbers, rebuilt from raw counting. You think you know this. You don't.LOGIC & PROOFThe machinery of certainty. Learn to argue so well reality has to agree.SET THEORYEverything is a set. EVERYTHING. The periodic table of mathematics.ALGEBRA COREArithmetic with the masks on. Solve for the unknown, every time.FUNCTIONS & GROWTHMachines that eat numbers. Curves, growth, and the art of the inverse.GEOMETRY & TRIGTriangles and circles — the load-bearing shapes of the universe.VECTORS & MATRICESArrows and grids of numbers that move entire planes around.VECTOR SPACESLinear algebra with proofs.
