NIGERIAN BOY AWARDED FOR DISCOVERING NEW MATHS FORMULA IN UK



A 12 year-old Nigerian boy named Master Chika Ofili was awarded for discovering new mathematics formula while solving his own assignment in UK.



The UK based Nigerian received "TruLittle Hero Award" for discovering a new divisibility by 7 in mathematics.



The head of the mathematics department at Westminster School, Miss Mary Ellis (Chika's Mathematics teacher) narrated how Chika discovered the new formula while solving a holiday assignment.


She said that she gave Chika a book called First Steps for Problem Solvers (published by the UKMT) to study during the holidays. The book had several divisibility tests which are used to quickly work out whether a number is exactly divisible by either 2, 3, 4, 5, 6, 7, 8 or 9 before you start dividing, but had no easy or memorable test listed for checking divisibility by 7. 



He solved this and also had an algebraic proof to back it up. His new formula involves taking the last digit of any whole number, multiplying it by 5 and then adding 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.
