page 12. mathematicians just assume prime numbers go on forver... umm, NO! mathematicians have know for 1600 years that they do go on forever. if you multiply ever prime together and add 1 you will have a new prime thus we can prove that. (2 x 3 x 5 x7 x11 x 13 x 17 x 19 x 23x 29x 31 x37x 41 x43 x 47x 53 x 59 x 61 x 67 x 71x 73 x 79x 83 x 89 x 97 x 101 x103 x107x 109x 113 ) +1 is prime.
