So little is understood of numbers in Qabala because so many people regurgitate sources without question. One gross estimation is in Hebrew numbers. Pre-Masoretic "Biblical Hebrew" numbers are *symbolized* by letters, but not named after them. Here is 1-10.
Achad
Rakhama
Shalowsh
'Arba
Chemesh
Shesh
Shevah
Shemonah
Teshah
Ehser
