English citations of FOIL

  • 2003 February, Downing, Douglas, Algebra the Easy Way, 4th edition, →ISBN, OL 3561086M, page 90:
    "We can use the word 'foil' to remember the procedure!" the professor suddenly realized. "We need to remember:
    First times first
    Outside times outside
    Inside times inside
    Last time last
    If you put them together they spell F-O-I-L — or FOIL."
    We decided to call this the FOIL method for multiplying binomials.
