Set Identities...delta?

Okay there is a problem that looks like...

Let A = {for all real numbers -5 < x <= 2} and

B = {for all real numbers -1 <= x < 4}

I know how to find A intersect B and A union B...however I was wondering if someone could let me know what it means when finding "A delta B". Thanks!

    As I remember A delta B is the reunion of (A minus B) and (B minus A)

    Delta means "the change in."

    So that would be the difference of A and B.
