This approach reduced the number of steps to a finite number of possible differences between two primes thus made it possible to apply divisibility rules on composite numbers whereas (Chauthaiwale, 2012, Eisenberg, 2000 and Aldrin et al, 2013) discussed prime numbers only.
"We are being taught concepts as basic as prime and composite numbers," said Pawan, a student of psychology.
How are prime numbers used to build up composite numbers? How many prime numbers are there anyway?

The Greeks were the first to notice the difference between composite numbers, or those that can be broken down into groups of other numbers, and primes, those numbers that can't be divided by anything but 1 and themselves.
Sales of compact machines such as skid-steer loaders, mini-excavators and compact track loaders have been reasonably strong during this period, which has helped keep the composite numbers higher than they would have been otherwise.
