Math (Digit): count and balance I used all symbols it's saying all at mathematics digits.
It has to total math digit 10 such as- 0,1,2,3,4,5,6,7,8 and 9 .

(significant digits): 0,1,2,3,4,5,6,7,8 and 9. (signifying the empty place):

0 Number: it also make a same math solutions.

( Intrinsic value / Face Local value): depends any digit use of number value. (place value/ local value) : 

Step by step write several digits then depending her condition it mean place value or  local value of math.
Such as .666 three digits 6 please value 6 but right side 6 local value 6 from right side second and third of please step by step 60 and 600 666 = 100 ×6+10×6+6
Same place of math as a result  change  of  math but as result same it.

(BD system)

Step by step write of math make from right side Now first , second , third, four, five, six, seven, eight, such as:
