Chika Ofili, son of Ogochukwu Ofili (father) and Nma Ofili (mother) from Nigeria but residing in the United Kingdom is the 2019 recipient of the prestigious TruLittle Hero Award in the leadership category. He was awarded for coming up with a new mathematical formula. His profile on trulittlehero.com reads that “… he discovered a formula for Divisibility in mathematics called Chika Test which classify [him] as a Child Genius.”
Miss Mary Ellis, head of the mathematics department at Westminster Under School in London where Chika is a student said that he came up with the formula while working on his homework she had assigned. Chika Test helps easily identify numbers that can be divided by 7. The formula consists of taking the last digit of any whole number, multiplying it by 5 and then adding this to the remaining part of the number to get a new number. He found that if this new number is divisible by 7, then the original number is also divisible by 7.
