Use the "array processing" inherent in functions such as Plus and Times
that have the attribute of being Listable , namely:
C = A - (1/2)B
That's it! (You can do Simplify later. And even there, you don't need
to do any explicit indexing, but -- at least for a one-dimensional list
-- just use Map: Simplify/@C
