Thank you !!!

Really good effort and kindness for sharing tips on how to properly use a powerful calculator. As compared to those trying hard to 'BS" talk day and night about P-o-l-i-t-i-c-s to bait for AD-$. Imagine if NASA have this Casio 991, that is less than 50 bucks was able to do more during the early years 60s - 70s Apollo Space program.

For the solar charging one, can I use both battery and solar? If I use battery only, do I still need to charge it?

The battery cannot be charged. If the battery runs out of power and the light intensity is high enough then the calculator still working.
