Lizzy: Sara's sister has 4 small notebooks in her closet. Last summer she ordered 6 more notebooks and then lost 2. How many notebooks does Sara's sister have now?.
Me: Hmmm, let me think. I think this is the detailed solution:
Sara's sister has 4 + 6 = 10 notebooks. After she loses 2, she will have: 10 - 2 = 8 notebooks. Final answer: 8.
