How Do I Uninstall Libre Office

After installing Libre office on my mac, it worked ok for about 1 week, after which I have been unable to open it again. The icon is still on my desktop but it will not open as before. My OS is High Sierra. I would now like to uninstall Libre office.

I don’t wish to seem unsympathetic, but have you considered the possibility that perhaps the problem is caused by High Sierra?

Thank you for your suggestion, but this problem occurred before I upgraded to High Sierra. Any ideas/help would be most appreciated.

Sorry, a more expert Mac-user could help.

Are you serious?
Same way you uninstall any other software.

Actually, yes, I am serious. I am a new user of Mac after years of Windows and am totally confused with this new system.
