Understanding Poly Numbers and Calculus

Norman Wildberger introduces calculus concepts using poly numbers, focusing on composition, translation, and derivatives. He explains the composition of poly numbers and introduces translation as a special case, leading to the concept of derivatives and sub derivatives. The video also covers bi-poly numbers and Taylor polynomials, highlighting their symmetry and role in understanding calculus algebraically.
