These problems involve adding and subtracting integers, using real-life contexts like temperature, elevation, money, and movement. Remember:
- "Drop", "down", "withdraw" → subtraction (negative)
- "Rise", "up", "deposit" → addition (positive)
- Negative numbers represent values below zero (e.g., below sea level, below zero temperature, debt).
