Chika Ofili, a 12-year-old Nigerian boy based in the United Kingdom, has been presented with a Special Recognition Award for his new discovery in Mathematics.
Chika, whose parents are native of Imo state, used his passion and talent as a mathematician to discover a new formula for divisibility by 7 in Maths.
His new formula for divisibility of 7 is to multiply the last digit in the figure and then add everything together, then check if the new figure is a multiple of 7.
For example, to check if 7 can divide 532, the process is illustrated below:
53 + 2 x 5= 63
63, is a multiple of 7, hence 7 can divide it.
