The "critical line"........is at 1/2.....................9 is exactly halfway between 8 and 10..................3 is more or less halfway between e and pi...........closer to pi.........................................8 and 10.......are two apart from each other..........10 - 8 = 2................








9 * 2 = 18
9 * 3 = 27
9 * 4 = 36


1 + 8 = 9
2 + 7 = 9
3 + 6 = 9................etc................................and reflexive symmetry..........................9 * 9 = 81............81 and 18.......................................................2.7............is how e starts out...........9 * 3 = 27.................3 is more or less halfway between e and pi.................3 squared..........which is 9.......is halfway between two numbers........8 and 10.........whose respective square roots are close approx. for e and pi........................8 and 10 added...............are 18....................

e (Euler's Number)

The number e is a famous irrational number, and is one of the most important numbers in mathematics.
The first few digits are:

2.7182818284590452353602874713527 (and more ...)

It is often called Euler's number after Leonhard Euler.
And Euler is spoken like "Oiler".
