High-powered equations with one unknown variable were introduced in the Tang Dynasty, and their use was greatly expanded during the Song, Jin, and Yuan Dynasties, and a method of numerical analysis (the Horner scheme, which was introduced by Horner in nineteenth century) of high-powered equations with one unknown variable for ordinary real numbers and coefficients was discovered.
唐のころから一元高次方程式を扱い始め、宋金元の時代に大いに発展し、一般の実数係数の一元高次方程式の数値的解法（ホーナー法、ホーナーによる提唱は19世紀）を見出した。
