Let's say I have a list with the members 1 2 3:

How do I take the second list member and add to the first list member, and then subtract the last list member from it?

I know the object [Lexpr], but what do I write as the arguments for this object? Can I take the members one by one in a list and manipulate them mathematically with each other?

list-expression

if the length of the list is known, i would probably use [unpack] and [expr]
