Mathematics teachers and their education professors appear unwilling to change the way they explain basic K-8 level mathematics. So, for now, I'm pausing trying to help human math teachers and have started teaching AI how math really works. Have a listen and see what AI has to

Namaste @HRDMinistry , @ncert staff and Shri @DrRPNishank ji If I do not receive a response from you by 30 June, should I assume you have no interest in my research into #Indic maths that will improve India's primary level maths education? @AmitShah @PMOIndia @narendramodi

Q. WHY DO KIDS HATE MATHS? A. India's ZERO was defined as the sum of two equal & opposite neg & pos quantities. Yet my research proves ZERO was misunderstood in the Medieval Arabic world & Europe 😮 If you don't teach Āryabhaṭa, Bhāskara & Brahmagupta etc you don't teach maths!

Thank YOU for your kind words at this difficult time we're all in. It helps me be strong & keep struggling to get closer to our life goal. Together, we can revive the better Bharatiya Maths of Āryabhaṭa Bhāskara & Brahmagupta. 1 Sign ⬅️ 2 Share 3 Win!

@subhash_kak Subhash, my impression as a maths researcher is India's large population and extreme competition to get into IITs means the focus is on cramming for calculation-based tests. The world is moving away from calculation, and its associated 'tricks' to concepts and creativity.

Namaste India! Give me a JAI HIND! It's 2:40 AM Sunday morning. I'm working on shifting the 🌏 away from broken 🇬🇧 British maths to the better 🇮🇳 Bharatiya Maths of Āryabhaṭa and Brahmagupta They should be better known than Euclid and Newton. Retweet if you're with me! 🙏

1/2 SHUNYA + SYMMETRY ⇒ INDIAN MATHS Is our universe a decompressed zero in which physical matter energy and logical opposition emerged? A zero-sum universe & principle of conservation of matter & energy indicates India's ZERO is both the start & end of everything and nothing.

🇬🇧 vs. 🇮🇳 🇬🇧 Maths was built for 1, 2, 3... based on Greek philosophy & looking to the ground 300 BCE. 🇮🇳 more powerful maths was built for ...-3 -2 -1 0 +1 +2 +3... based on science & looking to the stars 628 CE. Some 🇬🇧 laws & rules are bug fixes needed for broken maths! 😮

950 CE ARABIC WHISTLEBLOWER❗️ Hindi letters NOT Arabic Numerals Al-Uqlidisi wrote on superiority of India's maths. Yet he didn't accept ZERO as a number & Arabs NEVER understood Brahmagupta's 628 CE definition of ZERO as a sum of equal positive & negative quantities. SHARE? 🙏

ABOUT ME On Friday 18th March 1983 I was rushed with a broken spine to an emergency ward of the Alfred hospital in Melbourne. So, I promised to fix maths education if I walked again. I was 21. If Podometic #BharatiyaMaths triumphs in the 21st C., thank your God & Brahmagupta.

In 1968 @ age 7 I noticed India's ZERO was missing from multiplication. In 1983 @ age 21 in hospital, I prayed my smashed spine would heal & promised to fix maths if I could walk. In 2004 I dreamed a Goddess created maths from ZERO via +ve & -ve dots 🙏

1/4 BAN BAD BRITISH MATHS! Is it child abuse? Brahmagupta's 18 laws of zero, negative & positive are the ONLY foundations of maths that should be taught in 🇮🇳 primary classes. The legacy of the 🇬🇧 British is maths that gives many children nightmares. E.g., -7 IS NOT < -4.

A WARNING!? British Colonists forced India to discard its maths roots. Adhering to (inferior) global maths via PISA testing risks hijacking India's future! The SMART thing to do is trial and test Indic Podometic vs. British Arithmetic in classrooms. Yes/No What do you say?🤔
