Array formula on Excel for Mac

Question

I need to call LINEST in Excel 2011 for Mac, I would say - this was a detective story. My laziness, my curiosity, all was here! I had a homework from university course to us

Answer 1

This doesn't seem to work in Mac Excel 2016. After a bit of digging, it looks like the key combination for entering the array formula has changed from ⌘+RETURN to CTRL+SHIFT+RETURN.
