About the Book
Most of mathematics is presented in this book, starting from the basic and elementary concepts to probing the more complex and advanced areas.
Mathematics is approached both from a theoretical point of view, expounding theorems and definitions of each particular type, and on a practical level, going on to solve more than 1,000 exercises.
The approach to mathematics is given by progressive knowledge, exposing the various chapters in a logical order so that the reader can build a continuous path in the study of that science.
The entire book is divided into three distinct sections: elementary mathematics, the advanced mathematics given by analysis and geometry, and finally the part concerning statistics, algebra and logic.
The writing stands as an all-inclusive work concerning mathematics, leaving out no aspect of the many facets it can take on.
