- Supplementary exercises and problems that help consolidate new knowledge.

At the end of each section, a test with review exercises on the entire section's material is provided. With this test, the student has the opportunity to check their knowledge and prepare for the review exam at school.

A glossary of mathematical concepts follows, where the concepts are listed alphabetically so that the student can easily and quickly find their meanings.
