=the format for hexidecimal.
not an efficiant compression, but easy to under stand.
mathmatical sulution as follows

number follow as 10=16 20=32 30=48 ect

2222.
(2161616) + (21616) (216) 2=8192+512+32+2=8738 2222=8738

a7df
(10161616)(71616)(1316)+15=15360+1792+208+15=15755 a7df=15755

be09
(11161616)+(1416*16)+0+9 =bla bla bla bla, who cares eg #0 is important

the numeric value =the commandline you are at :to know the numeric value this way has no value:as long as you know the value of a,b,c,d,e,f,0-9,you can tell
just by looking at it which value is higher or lower

this 16 digit format is also used for the comand line
eg.
48=H
68=h
69=i
70=j
7a=k
7b=l
7c=m
and on and on for text and programing code
