I have this term:

((x ,y, z))

and I need to describe in words that the x in this term should be outside the bars? Is this correct? outside the bars?

x ((y,z))

The position of the x doesn't matter, it could be also behind:

((y,z)) x

These - ( ) - are called 'parentheses' in English punctuation, but in maths they are called 'brackets'. In this situation I would say, 'x is outside the brackets'.
