To get feedback on my work to date, in December 20129 I gave lectures in six states of India: West Bengal, Bihar, Delhi, Andhra Pradesh, Madhya Pradesh and Maharashtra. I also gave a lecture on the superiority of the ancient maths of the Indian subcontinent in Kathmandu, Nepal.
Everywhere I went I received great feedback from both students and teachers who began to understand the maths of zero, positive numbers and negative numbers for the first time. I spoke on the mathematical laws of India and Brahmagupta at the following places.
