Magnetic field of two parallel wires with opposite current

1. Two parallel wires, each carrying a current of I = 3.1 A, are shown below, where d = 5.2 cm. The current in wire 1 is in the opposite direction of wire 2. Find the direction and magnitude of the net magnetic field at points A, B, and C.

See attached file for full problem description.

I don't know how to do the problem - I have to convert Telsas to μT, and when I did that, using Ampere's law for long, straight wires, I got 11.36μT, into the page for both points A and C, but they were wrong. I don't understand what equation I am supposed to use. I really need to know how to find the direction of the magnetic field as well.
