Is there a way to make it so that you can add a variable ahead of another

So I want to make it so that instead of combining the two integer variables which are accepted and getting their sum I want to place one number ahead of the other like 215 and 364 will give 215364

Sorry for not being clear but it such that the variables are integers and not predefined.

>Solution :

use strings by putting " " around the numbers in order to concatenate.
