12-year-old Nigerian wins special award for discovering a new Mathematics formula

<p>A 12-year-old Nigerian boy, Chika Ofili has been lauded and given <strong>the TruLittle Hero award</strong> for discovering a new way to divide in mathematics.</p> <p>Chika’s mathematic’s teacher, Miss Mary Ellis who is also the head of the mathematics department at Westminster Under School said the 12-year-old discovered the new formula while solving a holiday assignment.</p> <p>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.</p> <p>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 divisible by 7, then the original number is divisible by 7</p> <figure class="wp-block-image"><img alt="" src="https://www.yabaleftonline.ng/wp-content/uploads/2019/11/chik.jpg" /></figure> <p>The post <a href="https://pluxtime.com.ng/2019/11/12/12-year-old-nigerian-wins-special-award-for-discovering-a-new-mathematics-formula/" rel="nofollow">12-year-old Nigerian wins special award for discovering a new Mathematics formula</a> appeared first on <a href="https://pluxtime.com.ng" rel="nofollow"></a>.</p> <br /> <br /> from WordPress https://ift.tt/34XCOZh<br />
