asked:What is the difference in water bottles between Courtney and Farah?
16 − 8 =8
8 water bottles
  1. Read the whole story first, before picking out numbers.
  2. The numbers are 16 and 8. What to do with them comes from the story.
  3. Two amounts are being compared, and the question is the GAP between them. A gap is always a subtraction, even when the story never says 'take away'. So this one is a subtraction: 16 − 8.
  4. 16 − 8 = 8 water bottles — that answers "What is the difference in water bottles between Courtney and Farah?".
