Someone very rightly said: “God made the integers, every other number is  that the  work of  man. Now after more  than a century, no mathematician would deny the importance and utility of the developments that Kronecker railed against. Yet  I think  that a lot of  harbors some sympathy for his statement.  The integers hold a special place  within the  heart  of mathematicians.  Many of  the foremost  famous unsolved conjectures relate to the properties of the primes. More importantly, the integers are where we start mathematics: they are how we count.
