word 2013 operation on text

[dogufo]

good morning,



I state that my question on word office 2013 is rather pretentious:

it is possible in a word text 2013 to make a macro or a command that identifies a specific number (in my case a 4-digit number), perform an operation on that number ( in my case make a sum) and paste them immediately after a text with the result obtained?


thanks for an answer
