Before delivering tricks and techniques I want to tell something about myself. I Rajesh Chaturvedi have basic qualification in Mathematics only at intermediate level. I have post graduation in Economics and also have diploma in Electrical Engg.
But from childhood I always involve myself deeply in mathematics. I received the knowledge of mathematics from very good teacher. One of them is D.P. Singh who was retired Deputy Director of Jawahar Nvodaya Vidyalaya Samiti Lucknow. Due to such type of my involments Ihave clear concepts in fundamental mathematics and also become very good in physics. In 80’s decade a great Indian Mathematician was famous named Smt. Sakuntala Devi. I watch her shows on television. She performed several long operation of mathematics ( multiplication of large numbers etc) in seconds. Then I start to think why I cannot do the same certainty she was not a magician. She was great mathematician. I start trying for this task and I make myself able to do the same.
