Math Foundations

The intuition behind every AI algorithm, through code, not textbooks.

Start this phase on GitHub

Prerequisites: Complete Phase 0, or confirm that Python 3.11+ and Git work from the repository root.

First lesson: Linear Algebra Intuition

Run this command from the repository root:

python3 phases/01-math-foundations/01-linear-algebra-intuition/code/vectors.py

Keep the command, exit code, normalized-vector output, projection residual, and one sentence explaining why a matrix-vector product is a neural-network layer.

Next action: Change one input vector, predict the result, run it again, then continue to Vectors, Matrices and Operations.
