12 year-old Nigerian boy bags special recognition award in UK for new Discovery in mathematics
A 12-year-old Nigerian boy, Master Chika Ofili, who is based in the UK, has
bagged a special award for recognition after making a shocking new
discovery in mathematics.
Chika is said to have discovered a new formula for divisibility by 7 in mathematics.
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.
What does divisible mean?
In math, a number is said to be divisible by another number if the remainder is 0. Divisibility rules are a set of general rules that are often used to determine whether or not a number is evenly divisible by another number.
