Quran Numbers 18 and 81

As u know 18 and 81 are written in our hands in Arabic.

u must have heard these 2

18+81=99=Al Asma'ul Husnaa

81-18=63=the hijri years Muhammad(saw)lived.

now he found this:

when we write it like this:

18 81=1881=19x99

19 is the miracle of Quran(we are not submitters,if you want to see really Quran is coded somehow with 19,check www.quranmiracles.com
it is the miracle of Quran,not the miracle of Rashid Khalifa.)

99 is Al Asma'ul Husnaa (again) :)

and suddenly,i found this

81 18=8118=123x66

66 is the abjad of Allah(swt)

123 also means something but what?
