It depends on wether it is connected to a circuit
No, not unless it has batteries as well as solar panels. Most calculators have solar power and batteries now. But you wouldn't be able to see the screen if you were in a dark room anyway.

No, it is not safe to preserve dead batteries by putting them in the freezer. Freezing batteries can cause them to leak or explode, posing a safety hazard. It is recommended to dispose of dead batteries properly according to local regulations.
it works by you putting batteries in it.
Putting batteries in series will up the voltage of the entire circuit. Certain things need higher voltage, so you put your batteries in series. Putting batteries in parallel will not up the voltage, but will let the current last longer. Watches would be more of an example for that. You want watch batteries to last long.
Normally putting the batteries in series would have more effect.
car batteries
For Alkaline batteries i recommend putting in great sunlight or buying an electrical battery charger.
Yes, the Mythbusters have tested the myth about putting batteries in the freezer. They found that while it may temporarily improve the performance of some types of batteries, it can actually decrease the performance of others. Overall, they concluded that it is not a recommended practice.
Frozen batteries last longer unfrozen batteries.
the sunlight hits the batteries and powers them :)
No, putting cassette tapes in the freezer will not revitalize them. This will damage the tapes. However, putting batteries into the freezer will revitalize the battery charge.
