Setting permissions using symbolic notation has some advantages over numeric, including the ability to add or subtract permissions. Another advantage may be that there's no math involved in setting permissions, a user would choose which flags to set r for read, w for write, and x for execute and then assign them to the file using chmod. Symbolic mode however requires more typing on the command line.
