Windstorm: Sum

We are all of us
equations – x's and y's and z's,
variables and values all adding
to a whole.
To be made of one value is to be
Incomplete.
x = ?

X can be anything and nothing
– a circuit left open.
A letter, a variable alone, has no value until
connected to others of its kind,
in a wondrous chain of
values.
Removing a link will not always equal
a negative,
but adding a link is not always
positive.
Taken or attached, each link
each trait – each value,
it all determines
the Sum.
z + y - c = I am

Note: I'll be adding another later, but semester's off to a rocky start thanks to Harvey so this is the most writing I've managed this week.
