Let me work through each subtraction problem step by step using the number lines.
Problem 1:
- Blue arrow goes from 0 to 7 (starting point is 7)
- Orange arrow goes backward from 7 to 5 (subtracting 2)
- So: 7 - 2 = 5
Problem 2:
- Blue arrow goes from 0 to 5 (starting point is 5)
- Orange arrow goes backward from 5 to 3 (subtracting 2)
- So: 5 - 2 = 3
Problem 3:
- Blue arrow goes from 0 to 6 (starting point is 6)
- Orange arrow goes backward from 6 to 3 (subtracting 3)
- So: 6 - 3 = 3
Problem 4:
- Blue arrow goes from 0 to 7 (starting point is 7)
- Orange arrow goes backward from 7 to 4 (subtracting 3)
- So: 7 - 3 = 4
Let me verify these answers are correct before providing the final answer.
Final Answer:
1. 7 - 2 = 5
2. 5 - 2 = 3
3. 6 - 3 = 3
4. 7 - 3 = 4
