1 方程:
今有上禾三秉,中禾二秉,下禾一秉,實三十九斗;上禾二秉,中禾三秉,下禾一秉,實三十四斗;上禾一秉,中禾二秉,下禾三秉,實二十六斗。問上、中、下禾實一秉各幾何?
答曰:上禾一秉,九斗、四分斗之一,中禾一秉,四斗、四分斗之一,下禾一秉,二斗、四分斗之三。
方程術曰,置上禾三秉,中禾二秉,下禾一秉,實三十九斗,於右方。中、左禾列如右方。以右行上禾遍乘中行而以直除。又乘其次,亦以直除。然以中行中禾不盡者遍乘左行而以直除。左方下禾不盡者,上為法,下為實。實即下禾之實。求中禾,以法乘中行下實,而除下禾之實。餘如中禾秉數而一,即中禾之實。求上禾亦以法乘右行下實,而除下禾、中禾之實。餘如上禾秉數而一,即上禾之實。實皆如法,各得一斗。
