Greg, you're not the first by a long shot to hate the Windows 10 calculator.
Though it has right-click to copy or paste, it's annoyed me for 6 months so like others I have replaced it for my use. One suggestion (here) <http://answers.microsoft.com/en-us/insider/forum/insider_apps-insider_other /windows-10-calculator-app-replace-by-microsoft/025783b7-8236-4963-86a7-692a b60a1115?auth=1> is a request for Microsoft to replace it with Microsoft Mathematics - there are nice images at that "Microsoft social" discussion page (also hate these acknowledgements to social media - "like", "trending", "social" - ugh. ) Ian Thomas Albert Park, Victoria 3206 Australia
