Numbers uninstall reinstall

Lately Numbers has been quitting unexpectedly on my MacBook Air and all the pre-installed templates are gone. Also it quits when working on formulas.

I'm thinking I could store documents in the cloud and uninstall and reinstall.

Is this possible? Will Apple charge me for a new Numbers App?


Solution 1:

Numbers is free from the app store, so reinstalling should not be a problem.
