  1. Return the area codes from a list of phone numbers (if the phone numbers are formatted as 315-333-4444, you would use the LEFT function to return the first three characters).
  2. Return the zip codes from a list of addresses (if the addresses are formatted as Syracuse, NY 13210, you would use the RIGHT function to return the last five characters).
  3.
