Cannot locate "Numbers"

I recently update/upgraded my Mid 2014 iMac to Catalina and naturally lost all access to anyWord Excel, etc files. I was trying to find "Numbers" to try and read files but no matter where I look or how I search I cannot seem to find it. Is there a way to restore it or re-download it? I may have inadvertently erased/trashed it during my upgrading. I'm not positive but I seem to recall some issues when I was upgrading.
