Math problems 1-35 talk about division. For example, problem 1-2 can be expressed in algebraic language as follows: for y = ax, z = bx, x + y + z = n, find x, y, z. The problems 36-42 talk about calculating the area of flat shapes, including squares, rectangles, trapezoidal approximations, and circles. The pi number, the ratio between the circumference and the circle, is taken as 3: 1. The problem group of 43-69 is for problems of scale, which is about the method of calculating the height of an object when the height of another object and the shadow length of the two objects are known. Also related to the ratio, there is a problem of calculating the number of objects that can be purchased with a sum of money when knowing their prices. Problem 70-85 talks about the problem of extracting numbers, algorithms to convert monetary units.

In addition, there is a problem about calculating square root, volume of straight blocks, and changing units. The book also has a partial tax calculation.
