Included in packages
In the textbook, the theory and tasks are divided into smaller parts to ensure that the learning material is easier to grasp. The textbook is prepared in such a way that the student can study independently. The exercises are collected in slides, where the first slides contain exercises based on examples, while the back ones contain more complex thinking components. The textbook is compatible with the 9th grade mathematics paper textbook, but also contains approaches specific to a digital textbook.
