  • "Every number is a factor of itself and a multiple of itself, so your totals are incorrect!"

  • "Actually Mrs Smith, if you read the question properly, you will see the word "other". Thus meaning numbers being factors and multiples of themselves is totally and utterly irrelevant.
    UR Set 7 sincerely hope this clears you misunderstanding."
  • Mr Walsh, ASCPS
  • Friday, July 29, 2011
  • "Aside form the other listed factors, surely 10 is not only a factor of 40, but also a factor of 20? Is that too simple?"
