“If you learn the concepts, you can develop your own methods…”
Ninth grade Math teacher Viren Mehta’s words inspired Chandrahas Halai, who had used them as his guiding principle to all that he does, including the writing of this book on Vedic Mathematics for beginners.
With a strong foundation of those concepts that he learned, Halai has shown in clear and simple steps that Vedic Math is not rocket science; in fact, it can be great fun! Using (simple) algebraic proofs, the author has explained the (Vedic Mathematics methods for) multiplication, division, squaring and cubing. The book has been divided into three sections and Halai suggests going through each one carefully, not skipping any of the steps detailed.
Aimed at students of grade 8 and above, and a good resource for teachers and parents too, as well as those training to take competitive exams, this volume is a novel way to discover that maths in general and algebra in particular can be great fun!

Thank you 'Indic Academy' for such a wonderful gift under 1000 Reviewers' Club.
While reading the book, a deep sorrow engulfed me. It reminded about struggling to memorize shortcut techniques of math during competitive exam and obviously long calculation of school days. Calculator was strictly provided. Only if we got this book on during our school going age, life would never be same again.
The book is only about 225 pages and packed with plenty of exercises to make one expert in the field of Vedic Mathematics. The author tries to keep the book as simple as possible so that students and adults can able to smell the flavor of Vedic Maths. In this era, where snubbing tradition is in vogue, the author has done a splendid job to bring back forgotten Vedic Math for everyday's use.
Now, there are many institutions are teaching Vedic Math with mind boggling cost. Any serious student can be a master of Vedic Math just by studying this book with concentration. Hope this book will benefit millions of students in their career.
What a great book and introduction to Vedic Mathematics. India is the fountainhead of many sciences and mathematics and this is wonderfully brought out in this book. Educators as well as interested readers can both benefit from this book and unlock the treasure trove of Vedic India.
‘Vedic Mathematics Inside Out’ by author Chandrahas Halai is no other than a Vedic Renaissance and an astute gift to the modern Indian Civilization. Chandrahas Halai is a mathematic enthusiast and a consultant in the field of computer aided engineering and is an educator of various topics such as linear algebra, machine learning and engineering. Through this book he has revived and elucidated the Sutras which were put forth amongst the world by Swami Shankaracharya Bharati Krishna Tirthaji Maharaj. The book is well divided into three sections and the chapters pre-empts from basics to advance topics with clear logical methods and help us solve complex problems within seconds. The first chapter explains methods of multiplication described in Bhaskaracharya’s Lilavati. The methods in the book make us realise that we Indians had a treasure of knowledge and we were studying foolish methods imposed on us by the westerners. The further chapters discuss the Nikhilam Sutras and Upsutras. The practical examples shed light to the core logic of the sutras. The fifth chapter explains the cover of the book. The intersecting lines give a different perspective to the multiplication of numbers. The division algorithm, squaring and cubing long digit numbers in the later chapters, give a fundamental base. This is a literacy India needs. As the author emphasises, this book is to be practised and not merely read.
As a school kid, I had a hate-love (in that order) relationship with mathematics. Never enjoyed it until high school. In fact, it was singlehandedly responsible for lowering my grades until then...hehe. Things changed when I was introduced to my tuition teacher (forever indebted to him) who had a very simple mantra to learn this subject - practice! How my hatred turned into unconditional love after that is a fascinating tale (Used to look for excuses just to learn it)!
For a beginner in Vedic mathematics, this book comprehensively covers multiplication and also explains division and powering in great detail. The author has explained all the concepts logically and lucidly. The "how" and, more importantly, the "why" of each topic has been vividly explained, with words and figures (you can actually visualize it). The book is neatly divided into 3 sections (8 chapters). The first section (consisting of 5 chapters) teaches Vedic multiplication in-depth. The next two sections provide a strong base to learn division, squaring and cubing. The second section (2 chapters) is completely dedicated to division (Nikhilam and Straight). The last section (1 chapter) is on squaring and cubing long digit numbers. All the concepts have been very well explained and we have exhaustive exercise material on each of them. I practiced them on a notebook (took me back to my school days :-)).
Highly recommend this book to high school students (and their parents and teachers) and any mathematics enthusiast. I'll be gifting this book to one of my friends' kid and it will hopefully help them. It would also be great if this book is introduced in schools (How I wish I had this book then!). My gratitude to Swami Shankaracharya Bharati Krishna Tirthaji Maharaj who discovered these sutras over a century ago.
Thank you Indic Academy for this initiative. Thank you Chandrahas Halai for this gem. Looking forward to reading many more of your books.
