Once upon a time, a 11-year-old child hated maths. Until the numbers started talking to her. Slowly, she stepped into the world of numbers, much like Narnia, and discovered a land of wonder.  These shortcuts were created by the child at that age, and have been written, years later, in much the same langauge. Some of the tricks are well-known now, and are a part of Vedic Maths. But this book is from the original notes of the child.  If you are a child who thinks numbers are weird and insurmountable, this book is for you.  Yes, this book is also an important foundation for aptitude tests and competitive exams. But that is not why it was written. It was written to take you to the magical land of numbers.
