Microeconomic Theory- An Intuitive Approach With Examples -mit Press-.pdf - Advanced

This text is famous for its "Step-by-Step" approach. Standard grad texts (like Mas-Colell) state a theorem and move on. Muñoz-Garcia proves the theorem using specific numbers (e.g., $u(x,y) = x^0.5y^0.5$). Do the math along with the book.
