The theory of the book is not that good but it contains wonderful solved Examples. It also has huge number of questions of very good quality and the book doesn't have many corrections
This book expands on many concepts introduced in Class 9, and if you didn’t fully understand most of that, it’s going to be much harder to grasp the material here. A lot of important points and concepts are hidden away in some paragraph somewhere, and some chapters are so mediocre in their explanations and illustrations that I end up googling just to understand. Why are so many important details buried in text? Shouldn’t they be made clearer?
All that being said, the book does do a good job of keeping math interesting in most chapters, at least for me. One chapter I especially like is the last one, which ofcourse isn't in the syllabus.
Mathematics is essentially a branch of logic and reasoning, and the chapter "Proofs in Mathematics" bridges the gap between the two. This chapter is particularly interesting to me because it's more abstract and conceptual compared to the other chapters. It involves logical reasoning, deductive reasoning, and step-by-step justification of statements and is also foundational for more advanced mathematics.
Some other chapters I like include:
Real Numbers Trigonometry Pair of Linear Equations in Two Variables Quadratic Equations Arithmetic Progressions Areas Related to Circles Probability The other chapters I find boring, difficult, or both.
A lot of students struggle with mathematics, and some blame the book for it. I don’t think that’s entirely fair. While the book does have its flaws, I believe it’s good enough and simple enough to be taught to a 15-year-old if have the will and time to engage with it.
Even after seventeen years of intensive therapy, a soul cleanse, and maybe a lobotomy, I still wouldn’t recover from the mental trauma this book inflicted upon me.
