Chika Ofili
A 12-year-old Nigerian boy based in the UK, Chika Ofili made history after making a new discovery in the field of Mathematics.
Chika Ofili was awarded at the TruLittle Hero Awards for discovering the new formula for divisibility by seven in mathematics.
The new formula involves taking the last digit of any whole number, multiply it by 5 and then add it to the remaining part of the number to get a new number. If this new number is divisible by 7, then the original number is divisible by 7.
