Turning off a calculator is a simple process that can be done in a few steps. First, locate the power button on the calculator. It is usually located on the top or side of the device. Once you have found the power button, press and hold it for a few seconds. The calculator will then turn off.
If your calculator does not have a power button, you may need to remove the batteries to turn it off. To do this, locate the battery compartment on the back of the calculator. It is usually held in place by a screw or a latch. Once you have found the battery compartment, open it and remove the batteries. The calculator will then turn off.
