C is a reserved word. To avoid conflict with built-in names, always start your names with a lower case letter.
n = 3;
mA = Array[a, {n, n}];
mB = Array[b, {n, n}];
mC = mA + mB/2
{{a[1, 1] + (1/2)*b[1, 1], a[1, 2] + (1/2)*b[1, 2],
a[1, 3] + (1/2)*b[1, 3]}, {a[2, 1] + (1/2)*b[2, 1],
a[2, 2] + (1/2)*b[2, 2], a[2, 3] + (1/2)*b[2, 3]},
{a[3, 1] + (1/2)*b[3, 1], a[3, 2] + (1/2)*b[3, 2],
a[3, 3] + (1/2)*b[3, 3]}}

=============
I want to subtract array A by 1/2 array B and put it in array C. I need something like this except more complicated later. This is what I have thus far:
C:=C=Simplify[Table[A[i]-1/2*B[i],{i,1,9}]]
