First of all, Gujarati digits take the range of Unicode code points 0AE6 to 0AEF and have the same order than traditional Westen Arabic digits 0 to 9:

Therefore, you can, for example, convert from Arabic to Gujarati and back using a simple shift. To get a code point from .NET char, you can use these functions:

Now, I advise the following scenario: don't try to do numeric arithmetic on those strings. Instead, develop two methods: parsing a Gujarati number into the numeric type your are interested in (say,
int or
long) and representing the number as a Gujarati numeral string. In other words, create two "Gujarati versions" of functions analogous to
int.Parse (or
int.TryParse) and
int.ToString. When it's done, you can parse strings to number, do your addition (subtraction, multiplication) in numbers and then represent numbers as strings.
