Why can’t there be a simple but full-featured spreadsheet application that not only can do simple spreadsheet tasks but also has a full-featured function set that can be used for slightly more sophisticated tasks?

But … I haven’t been able to figure it out, short of writing a bunch (40+) of functions by hand… ar!
Apparently, there’s an “advanced sum” feature that’s available as an add-on, that helps you build fantastically complex “if statement” functions in a few clicks. …
