You are able to add two numbers togehter. Congrats!

But that doesn't change the facts that Natsu's age isn't known and that the people caught in Fairy Sphere did not age during those seven years they were caught within and thus aren't any older than at the beginning of the Tenrou arc... well... some are 3 month older, but certainly not years.
