In 1950 he became a lecturer at the University of Southern California, where he stayed until 1966. In 1967 he wrote his very popular book, Mathematical Quickies: 270 Stimulating Problems with Solutions.Mathematical Quickies: 270 Stimulating Problems with Solutions Review by Google BooksReview of Mathematical Quickies by Charles W. Trigg Howard Eves, University of Maine A reviewer said, "For the mathematics enthusiast of any age or level of sophisitcation, this stimulating treasury of unusual math problems offers unlimited opportunity for mind-biggling recreation."
