Cutting off a Character from a String

I just have a small question - how can I cut off the leading character
of a string? For example, in my case, I have a list of telephone numbers
with a 1 at the beginning... I need to say that if the string is 11
characters long, delete the first character. How can I do this? I am
very new to RoR and the RDOC is kinda confusing...

Thanks in advance,

if string.size == 11

or even better...

string=string[1..11] if string.size==11

This is where i get all my string info... great site...

Thanks everyone!
