[Contents] Essential Thinking: MIT-Style Problem Setting & Problem Solving - 1 Book Toyo Keizai Inc. By Takashi Hirai Published February 2015 Overall, there is some soiling. The cover, front cover, and back cover have stains and damage. There are corner folds. There are no writings or tears. The text is in a condition that can be read without any problems.
