Chika Ofili is a 12-year old Nigerian boy based in the United Kingdom. On Saturday 9th November 2019, he was presented with an Academic Hero Award at the TruLittle Hero Awards ceremony for discovering a new formula (with an Algebric proof to back it up) for divisibility by 7 in Mathematics.
The TruLittle Hero Awards is a ceremony organized by Cause4Children Limited aimed at recognizing, celebrating and rewarding outstanding achievements of remarkable children and young people under the age of 17years all over the country.
Chika’s new formula involved multiplying the last digit of any whole number by 5 and adding the result to the remaining part of the original number (i.e the whole number). If the result is a multiple of 7, then the number is divisible by 7.
