13 is the closest prime to the 1st zero in the R. zeta function...............1/2 + 14...i................pi starts out 3.14..............a 14............................................strange.....I got the idea that there is a prime f............with where the 1st zero is.................in double digits.............as all numbers............are different parts out of 0 - 9.............I thought single digit primes might be diff than others..........


Like this.........

2 + 11 = 13
3 + 10 = 13
4 + 9 = 13
5 + 8 = 13
6 + 7 = 13

summing...........the most basic process/operation in math..........
