  1. Words prevail over figures
  2. Interest runs from the date of the instrument, if date from which interest is to run is unspecified; if undated, from the issue
  3. If undated, deemed dated on the date of issue
  4. Written provisions prevail over printed
  5. If there is doubt whether it is a bill or note, the holder may treat it as either at his election
  6. When not clear in what capacity it was signed, deemed signed as an indorser
  7. If "I promise to pay" but signed by two or more persons, jointly and severally liable.
