    I recommend this book for those who want to make simple calculations a lot faster than usual. Be aware of some ERRORS I found in the exercises at the end of the book: - Q #1 in the Multiply by 11 section: 11 * 39 - Q #2 doesn’t involve multiplication by 11 (don’t worry though, the answer is there) - Q#1 in the Sum of the first n terms section: the answer should be 756 instead of 759 -Q#5 of the last mentioned section - Q #1 Section of multiply by 9, 99, 999 and also Q#4
