Since 1964 he has been on the faculty of mathematics, where he is now professor emeritus. He dealt with combinatorics and optimization, especially with mathematics education. He wrote numerous books on elementary mathematics (geometry, number theory, combinatorics, probability theory), and recreational mathematics (often at the Mathematical Association of America, MAA), with him in his own words using the book by Hans Rademacher and Otto Toeplitz of numbers and figures as a model.
Frequent are his expositions of problems at the International Mathematical Olympiads and other competitions.
Edsger West. Dijkstra called his Mathematical Gems "delightful".
