adding numbers

I have 2 ints , lets say 2 and 5
I want to add them NOT 2+5 = 7
I want to add them like this 2+5 = 25
how do I do this

Multiply the first by ten, add that product to the second.

wow thats a clever method thank you I thought I was going to have to convert them to strings

Actually I wondered if you weren't after a string. Pretty basic stuff actually. Working on a project?

You want to concatenate them.
