these I have done before also but the things on introduction page says that it's a book of improving calculation but it's not doing so highly it's just for the students of 3 to 5 class but not for people to have an competition there is need to decrease the number of eg.s and to increase the chapters with a nice number of tricks to solve each and every calculations in second overall the book is good for children entering in field of multiplications

The methods are good and different. It's definitely useful but there are many errors in the calculations and the answers are wrong. For example, 15x16 is 240 but the answer is given as 220. Other than that the methods are good. Overall its a very good ebook.
