Yes, and?  The answer is right above your question.

Do you mean a series of one or more or a series of
zero or more?  (Or 42 or more or...?)  Your problem
statements are piecemeal.

[-+.]* is zero or more.  [-+.]+ is one or more.

As Tomas pointed out, you need not escape the `-'.
But it's easier if you do.  If not, you need to group
the pattern that gets repeated:

\(-[+.]\)* is zero or more.  \(-[+.]\)+ is one or more.
