12 years Nigerian wins Special Recognition award for discovering a new Mathematics formula

A 12-year-old Nigerian boy, Chika Ofili has been awarded the TruLittle Heroaward for discovering a new way to divide in mathematics. 

Chika’s mathematic’s teacher, Miss Mary Ellis who is also the head of themathematics department at Westminster Under School said he (Chika) discovered the new formulawhile solving a holiday assignment.

She revealed 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 anumber 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. 

Chika however 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 divisibleby 7, then the original number isdivisible by 7.
