Chika Ofili, a young Nigerian-British math prodigy, made global headlines after discovering a new mathematical formula while still in middle school—an achievement that has earned him praise from mathematicians, educators, and global leaders alike.
While reviewing divisibility rules, Chika discovered a new formula to test divisibility by 7, which had not been formally documented in mathematical literature. This breakthrough came while he was working on a math holiday assignment, leading to a remarkable contribution to number theory at just 12 years old.
To check if a number is divisible by 7, remove the last digit, double it, subtract it from the rest of the number, and repeat. If the result is divisible by 7, so is the original number.
Chika’s discovery earned him the TruLittle Hero Award in the UK for academic excellence. His story soon went viral, inspiring countless young students around the world to pursue mathematics with passion and curiosity.
Born to Nigerian parents, Chika’s journey has been a beacon of inspiration, especially in African and diasporic communities. He has become a role model not just for his genius, but for his humility, enthusiasm, and dedication to learning.
Educators and institutions across the globe have highlighted Chika’s discovery as a reminder that great minds can emerge from any corner of the classroom, and that nurturing curiosity is key to breakthroughs.
Chika Ofili’s name now sits proudly in the world of mathematics — as a symbol of youthful brilliance, curiosity, and the boundless possibilities of the human mind.
