If you have immense love for mathematics like me, this book is a treat for you. Maths is fascinating and getting to explore more of the subject through new dimensions is interesting and satisfying. The book itself is an assortment of different facts, tricks, tips, shortcuts and lots of fun. Aditi and Sudhir have a lot of experience with math workshops and have shared a lot of their experiences and wisdom in the book.
I went through the book, chapter by chapter at different intervals of time, letting the concept or material to sync in. It is not an advanced book but it is important to savor the treat than swallow the whole in one go. I really enjoyed reiteration of few concepts, learning some new ones of which some are very helpful.
There are a few applications in the beginning which the nerd inside me savored. I smirked at a few smart facts and tips. I also enjoyed solving some of the problems. Overall an enjoyable book and can be read at all levels of knowledge of the subject. I will be dreaming numbers!!
