Vedic Maths for 8th (CBSE Curriculum) - Vedic Math, #1

Mathematics is a tricky subject. Those who love, enjoy it much and those who don't, feel it's boring. I lost interest in mathematics while in 7th class. Based on whatever I remember, it was mainly due to a lack of understanding of negative numbers. By nature, I am a kinaesthetic person and therefore I refuse to accept anything unless understood thoroughly. Generally, just memorization doesn't work for me and the same thing happened to the multiplication of negative numbers.
Our teacher presented them as rules and I refused to accept them at face value. One year later my cousin's grandfather started living with us and he had a great interest in teaching. Moreover, his concepts in mathematics were extremely clear and he could answer all my crazy questions. This retriggered my interest in mathematics. The whole journey was so joyful that I wish everyone get a grandfather like him who is at home to help with fundamental questions in studies.
When I started thinking about developing books as per the curriculum, the next question was which board to follow. After a bit of research, I got to know that CBSE is the most popular board in India and therefore I decided to develop Vedic Math books for the CBSE curriculum. Finally, I had a choice of developing books from class I and I decided to develop the first book for class VIII. Class VIII is the foundation for board exams and therefore I felt this is the right time to start strengthening our knowledge, skills, and abilities.
The book is designed in such a way that all required methods from Vedic math are covered here and the student need not refer to any other book to learn the basics. Secondly, numbers (data) are represented in pictorial format or charts wherever appropriate. This certainly simplifies the learning. I have explained principles wherever relevant. This shall help the pupil to understand them further and apply them confidently.
