2. Memory Functionality Many calculators have memory functionality, which allows for storing and retrieving previous calculation results. This is very helpful for performing continuous mathematical operations. 3. Unit Switching between Degrees and Radians For trigonometric function operations, calculators support both degree and radian units. When a unit switch is needed, you need to press the corresponding switch key. III. Usage Precautions 1. Correctly Use Keys When using a calculator, you should ensure that each key is pressed correctly. Incorrect key presses can lead to incorrect calculation results. 2. Pay Attention to Display Screen Clarity When using a calculator for calculations, you should ensure that the display screen is clearly visible so that you can observe the calculation results. 3. Protecting the Calculator To extend the lifespan of the calculator, it should be kept away from harsh environments such as high temperatures and humidity. At the same time, regularly cleaning the surface of the calculator can help maintain its good condition.
