If you're doing what I *think* you're doing then you might try using 
\edef\x{\x 1 add}, but depending on what you're actually trying to do I 
can think of many different things that could be going wrong. If \edef 
doesn't solve your problem, please post a complete minimal example that 
demonstrates it.
