Have tried all week to figure this one out .Probably something that I should know right away.
13 letters 1,4,1,6,1
Equation:solution(if Roman and atomic numbers)Z=F
I think it's x plus y equals but can't decide the final letterWant to put z but don't know why. Thanks in advance. ,

The Atomic Number is traditionally represented by the symbol Z.

Many thanks Aquagility. I can stop puzzling over the answer now.

There was a thread about this a few days ago and I don't think the answer is that straightforward as it is linked to the other clues - in this case x+y = 49 which is the answer to clue F, so I've plumped for the letter F rather than Z.

Thanks pjwillcox. Can see your logic and guess you could be right. Will be interesting to see the answers next week.
