Is this wrong or am I stupid?
In the sum where we have the evaluation bars, I can see that if n = +1, then the coefficent is +1/2 * j, and if n = -1, then it is -1/2 * j. But in the answer below it says n = +- 1, then -+ 1/2 * j, which I interpret as if n = +1, then the coefficient is -1/2 * j. Is this is a mistake or have I not understood something?

You are correct about the meaning of the minus/plus symbol.
The rest I'm not familiar with, unfortunately.

I figured it out, it's due to, above it is \dfrac{1}{2j} and in the answer it is \dfrac{j}{2}
j^{-1} property
:p

sneaky putting j in the denominator
