The 1st 8000 numbers.......have 1000 primes....more or less................that means........until 10,000......there is a gap of 2,000 to go...........to get to 10 ^4.........which is ten thousand..............- 2000...............- 2, 0.........the 1st zero on the X axis......at a rate....or 12.5% more or less................................2000 to go................240 is 12% of 2000.........so there are basically 1, 240 primes................under 10,000........the 1st number in 5 digits............on the positive side...........8000 with 2000 to go.....1828 in e..............there are 8 primes....under 20......28......the 2nd perfect number............and the sum of the 1st 5 primes.......imp........b/c 5 primes are the necessary and sufficient conditions........i.e........the minimum to connect single digits to double digits....just like a certain line.......at 1/2........also.............12.5 % is half of 25%.........1/2........the rate..........is halved from 100.............to 8000........................100/8000..................18..................half circle.....180 degrees....18 is a truncated one anyways...
