Kiev, Ukraine native Boris Pritsker worked as a math teacher in a special school for gifted and talented high school students with advanced programs in algebra, geometry, trigonometry, and calculus. His teaching experience led to his publication of numerous articles and problems in mathematical magazines in the former Soviet Union, United States, Australia, and Singapore. He published two books, Geometrical Kaleidoscope, Dover Publications, Inc., 2017 and The Equations World, Dover Publications, Inc., 2019. Both books are featured with positive reviews at Mathematical Association of America website. The MAA's Basic Library List Committee assigned the BLL rating to "Geometrical Kaleidoscope" and suggested that undergraduate mathematics libraries consider the book for acquisition.
