How do i turn value into something usable?

How do I turn a value into something i can use without the “-” negative value if there is one.

I have an “imageLoaderHost” movieclip and I need it’s x position to be usable wherever its at. for instance:

if imageLoaderHost is at -1258(x position), I need “b1” to go to 1258 (without the “-” as you can see).
