There are 8 mathematical compilations: the first 1 is arithmetic; In chapter 2, continuous multiplication is proposed. The third part is about plane geometry and solid geometry, including the problems of finding the proportional average of two line segments, arithmetic average, geometric average and harmonic average, and the problems of representation on a geometric figure, which reveals how the regular pentahedron is connected into a ball. In the fourth chapter, the three circles circumscribe each other, and the archimedean spiral, Nicodemus Clam Line and Hippocrates Secant Line are also discussed in detail, and the bisector at any angle is involved. The fifth chapter is about area and volume; The sixth part is a review of the work of previous astronomers and mathematicians; The seventh chapter expounds the analysis and synthesis of terms and the difference between theorems and problems; The eighth article focuses on mechanics.

Unfortunately, some chapters in the math compilation are also missing. In addition, there are other works of the Baptist Church that annotate the works of Ptolemy, Euclid and others.
