Finding a 4-digit number is trivial; you haven't given anywhere near enough detail, though, as to what the parameters for this 'operation' might be. For example, how does one determine whether to add, subtract, divide or multiply (in your case a summation), and what the other value(s) in this operation might be?

thanks for your kind reply;

the argument is that I have a long text in word 2013, with several years dates inside (e.g.: 1235 A.D., 1476 A.D., 238 B.C. etc.).

So, I need to find a way to add in the text, concurrently, after these dates another date increased of 2698. E.g.:

1235 A.D., to become in the text after the 'operation': 1235 A.D. (chinese year 3933)

238 B.C., to become in the text after the 'operation': 1235 A.D. (chinese year 2460)



Is that possible to do in word 2013? let me save time and energy

Thanks again for your reply
