Quantity A Quantity B
y/2 x/2 + y/2
0 x/2

We have no information about x's sign
For example:
. x = 1 --> A < B
. x = -2 --> A > B

A: y/2
B: (x+y)/2

B = x/2 + y/2 so B = A + x/2
x can have different values. If x is negative then B is less than A.
If x = 0, A and B are equal.
If x is positive, then A is less than B.
