0 - 9.......all single digit numbers..............10 of them...............................1 - 9...............all single digit counting numbers................integers......................9 of them..........together.........the two sum to 19..................with mirror sym....91........90 degrees............like in a right triangle .................like 0 - 9................all 10 single digit numbers..........spun......like 90 degrees is 1/4 of the Cartesian plane...........like 14i........the 1st zero........................


.........9 single digit counting numbers......1 - 9.........................all single digit counting numbers........1/10.................is the 1st fraction in the harmonic series......to have a double digit den.......................it is the 10th term......in the h.s........but the 9th fraction.........like 19........10 + 9 = 19...............imp...........b/c..............1/9 + 1/10.........the 1st jump from single digit denominators to double digit denominators...............1/9 and 1/10.........becomes......19 and 110.............they are 91 away from each other.........b/c 110 - 19 = 91................reflex sym....19 and 91 are...........there are 90 integers in the gap between 19 and 110...............90.........like 90 degrees.........1/4 of the Cartesian plane.............1/4 like 14i......................and 90 degrees is what defines a right triangle........the 45/45 and 30/60 right triangles seem imp in this..............
