Most students fear General Equilibrium (GE) because of the fixed point theorems (Brouwer, Kakutani). This book does not skip the math, but it provides a brilliant metaphor:
The book "Advanced Microeconomic Theory: An Intuitive Approach With Examples" is available for download in PDF format from various online sources, including the MIT Press website. The book can be downloaded for free or for a fee, depending on the source and the intended use. Most students fear General Equilibrium (GE) because of

Muñoz-Garcia starts with a story. "Consider a grad student choosing between ramen and coffee." He uses numerical examples first (e.g., Utility = x^0.5 * y^0.5 with specific prices and income). He solves for the optimal bundle numerically. Then he introduces the Lagrangian. Then he derives the Slutsky equation intuitively: "The total effect of a price change = Substitution effect (relative price change) + Income effect (purchasing power change)." Then he introduces the Lagrangian
