  1. 1,250,000 · 2,450,000 - 1,200,000 = 1,250,000.
  2. 2000000 · 1,250,000 + 750,000 = 2,000,000.
  3. Add, then subtract, then add · Ordering nails adds to the stock, selling nails subtracts, and ordering again adds. Follow the story in order: add, subtract, add.
  4. True · That's exactly how many two-step problems work: the first answer becomes part of the next step.
  5. Mental math · These numbers are small and simple, so you can add them in your head without writing anything down.
  6. False · Karl is wrong: mental or written methods often win, and the choice needs justifying.
  7. 2410000 · 2,350,000 + 150,000 - 90,000 = 2,410,000.
  8. 6,172,000 · First add the people who moved in: 6,325,400 + 458,900 = 6,784,300. Then subtract the people who moved away: 6,784,300 - 612,300 = 6,172,000.
  9. He should have subtracted the refunds instead of adding them · A refund means tickets are given back, so the total goes down. Malik needed to subtract, not add.
  10. 1,070,000 · 3,750,000 - 2,680,000 = 1,070,000.
