Just recently the @ sign has been appearing in my functions in Excel 365 (or I've only just noticed it).

I have looked up why this is and - confession time - I am stuggling to understand the explanations about "implicit intersections"

The odd thing is that the appearance of the @ seems to be quite random and my functions never seem to need it.

I would be most grateful if someone can explain this in non-jargon language please.

Thanks
