1229.primes...........under.......the 1st number with 5 digits.........10 thousand..............23 + 29 = 52............5/2 = 2.5...................at 100 the percentage........of primes per the area they are in.....is 25 %.......they half at about 8000........b/c 7919 is the 1000th prime.................................97 is the last prime in 2 digits and the 25th prime.....................7919.......................79 is 97 backwards..................also 7919 is 81 from 8000............1000/8000 is 1/8 which is 12.5%..........................patterns.......8000 lacks 2000 to get to 10,000..................about 229 primes more...................-2000 to go to get to 10 ^5...........another 25?  - 2, 0..............1/2..................1828......in e....................





I was more or less right.......like Gauss' guess.................it is more or less in the right direction...

All Prime Numbers to 10,000. There are 1229 prime numbers between 1 and 10,000. They are given here below.
