Chu Shih-chieh(jo͞o shŭ-jĕ), fl. 1280–1303, Chinese mathematician. He contributed to the study of arithmetic and geometric seriesseries,
in mathematics, indicated sum of a sequence of terms. A series may be finite or infinite. A finite series contains a definite number of terms whose sum can be found by various methods. An infinite series is a sum of infinitely many terms, e.g.

Chinese mathematician of the 13th century. In his treatise Precious Mirror of the Four Elements, Chu described a method for solving numerical equations similar to Horner’s method and presented methods for forming equations. Chu developed a notation for equations of higher degree in four unknowns and solved a number of problems that reduce to such equations.
