Think Like A Maths Genius: The Art of Calculating in Your Head

Super book.Only thing is that we should be patient.So that we can have a command on mathes.I read many bookson this speed math topics but they are tedious and we are not getting any motivation to complete them.This is the best book I ever read on speed math techniques.

Good for fast calculation for maths best book for Olympiad when you don't have enough time to solve. I preferred you to take this book ( don't miss)

Writer/genius is very famous for his brain powers. His techniques are very helpful to increase brain capacity to a maximum level.I have already seen the improvement of my calculations and use it every day.

Very good book for fast calculation.

It is very useful book for me . It has use very simple mathod to explain.after few days I am able to solve many types of question mantaly.

Such tactics are better explained with videos rather than written books.
