Ampere's circuital law states that the closed-loop integral of B.dl (also called the 'circulation of magnetic field') always equals mu_not times the enclosed current.

I have a question, when you did the first equation with (-I1 + I2) then went to the second equation (I3-I2) it went from the first I being negative then to the first I being a positive, does it matter the order you place the I in for the equation?
