Meet Chika Ofili, Little Nigerian Who Makes New Discovery In Mathematics

Meet Chika Ofili, Little Nigerian Who Makes New Discovery In MathematicsChika Ofili is a young mathematics genius who rewrote his by inventing a brand-new mathematical formula that won him the “TruLittle Hero Awards” in the United Kingdom Ofili received the award at a yearly event that honors great accomplishments of exceptional children and young people under the age of 17 from all over the United Kingdom.

Ofili, who is also the head of Westminster Under School’s mathematics section, discovered the formula while working on a holiday assignment, according to his teacher Mary Ellis.

According to reports, Ellis gave the young man a book with several quick tests for determining whether a number is precisely divisible by the numbers 2 to 9, but the book lacked a standout test for determining divisibility by 7.

Ofili created a novel formula and provided an algebraic proof for it.

What mathematical Formula Did Chika Ofili Invented?

He is credited with developing a novel
mathematical formula for divisibility by 7.

According to his method, you can generate a new number by taking the final digit of any whole number, multiplying it by 5, and then adding the result to the remainder of the number. The initial number is also divisible by 7 if this new number is also divisible by 7.

For instance, the procedure is demonstrated below to determine whether 7 can split 532:

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 contained 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.

However, there was no test for determining divisibility by the seven mentioned. Since there is no simple or memorable test for dividing by 7, this was left off the list, but Chika Ofili was able to answer it.

He found that you can create a new number by taking the final digit of any whole number, multiplying it by 5, and then adding this to the remaining portion of the number. The initial number is also divisible by 7 if this new number is also divisible by 7.

Chika then gave a presentation of his new formula to the teachers of the school. Miss Ellis then hired an unbiased math expert to test the hypothesis. Simon Ellis, her younger sibling, who also taught math.

He put the idea to the test and produced an algebraic justification. He also found that the test is accurate if the last digit is multiplied by 12, 19, 26, and 33 before being added to the remainder of the number.
