Another 9 to match the ten - 9's u get by overlapping the pf with the negative integers?   5/4.......using the zero dimension..........5 + 4 = 9.......another 13 as well........7/6....using the zero dimension, ignoring convention that u cannot do that............u get 13.............7 + 6 = 13............



Euler's product...................with an S of 1.......for the primes..........begins..................2, 3/2, 5/4, 7/6....................two......could be written as (1 + 1)...........binomials...........binomial expansion........two ter
