Nigerian Boy Awarded for Discovering New Mathematics Formula

TruLittle Hero award a 12-year-old Nigerian boy, Chika Ofili for discovering a new way to divide in mathematics. Chika discovered the new formula while solving a holiday 
Miss Mary Ellis who is Chika’s Mathematics’ teacher, also the head of the mathematics department at Westminster Under School 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 that 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.
