When I first bought this book, I was dumbstruck at the advanced maths of the Soviet Union. Written around 1989, This book is just fabulous. It has wide ranging topics from Combinatorics to Induction. It lets you yourself prove things.
A very interactive book, I have benefitted greatly.
This book is also featured in the reference of IMO.
I strongly recommend this book for those who are appearing in RMO.

I bought it in 10th but never read it properly at that time. But when I started doing it seriously in 11th, I was amazed at its approach. Its teaching style is completely different from routine Indian mathematics books.

It first gives the reader some basic ideas and concepts and then teaches further important concepts through problems. It game me a sense of accomplishment as I progressed further. This problem solving approach is what lacks in routine books. Definitely an eye opener.

Must b...

Its a book that rekindles joy and happiness in me. And here I write a true review for it

Very helpful for students wanting to appear for any maths related entrance exams. This is a recommended book for CMI entrance and if you master it, you can get into CMI quite easily.

excellent but four stars only because answers were not provided to some questions.
too good for olympiad foundation.the type of attention paid to chapters like divisibility is amazing.
combinatorics is excellently covered. a masterpiece of russian mathematical intelligence

I strongly recommend this book to all the children to get introduced in an intuitive way to some of the basics of Mathematics in Calculus, Number Theory, Puzzles, etc. The way the authors have written this book is awesome. It feels like reading a thriller novel. Simply superb.

This book is for enjoying mathematics.
Don't use for olympiads
