4. Use mode switching: Some advanced calculators have multiple modes, such as degree systems and binary systems. Learning to switch between these modes can help handle more types of calculation problems. **Common Issues and Solutions** 1. Battery depletion: When the calculator's battery is low, the calculation results may be incorrect. Regularly replacing the battery or using rechargeable batteries can avoid this issue. 2. Keypad unresponsiveness: If the keys become unresponsive or sticky, it may be due to keypad aging or accumulation of dust. You can gently clean them with a soft cloth or send them in for repair. 3. Blurry display: After prolonged use, the display may become blurry or dim. You can use professional cleaning agents to clean it or send it in for repair to restore display clarity. 4. Data errors: Any small error in inputting data can lead to incorrect results. Therefore, carefully check your data before inputting it and perform calculations only after verifying its accuracy. 5. Inability to handle complex problems: If you encounter problems that cannot be solved through basic operations, try using more advanced functions or modes, or seek help from other tools. 通过掌握这些技巧和注意事项，我们可以更有效地使用计算器，无论是学生还是职场人士，都能从中受益匪浅。
