Petition to Teach Superior Zero-Based Maths @ 8000 Signatures

Arithmetic is via Ancient Greek maths missing ZERO. So, ideas like -3 < -1 and 0⁰ = 1 when 0¹ = 0 and – × – = + are RULES not REASON

PodometicTM is via Brahmagupta's Sūtras for Negative, Zero, Positive, Laws of Physics & TEACHING


Many fear maths. Why?

British Maths was built for 1, 2, 3... based on Ancient Greek philosophy and looking to the ground 300 BCE. It did not have Zero and Symmetry at its core.
India's Superior Maths was built for ...-3 -2 -1 0 +1 +2 +3... based on science and looking to the stars 628 CE.

Brahmagupta defined zero as a number and wrote his simple laws of maths in the 7th century. Yet the definition of zero and laws of (+ – × ÷) on positive and negative numbers were not understood in the Arabic world!

Maths is confusing today because Europe got its knowledge of India's maths via the Arabic world. So please sign this petition to request schools teach INDIA'S BETTER MATHS available to everyone in India FREE at www.podometic.in

Thank you for signing now

Happy memories from Indian Maths Tour #3

My 2020 vision is to relaunch Indian maths based on the writings of Āryabhaṭa, Bhāskara and Brahmagupta. You can download my slides free from www.j.mp/IndiasMaths 

To get feedback n my work to date, last month 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.

Patna Science College Patna University

INTACH New Delhi (Indian National Trust for Arts and Cultural Heritage)

Ananda Ashram Balika Vidyapeeth High School in Kolkata

AIMER Maths Education Conference, Indore
