I didn't see any other posts on this so maybe I missed where it was originally explained I the text, but it took me a long time to figure out what the || operator means.
I saw it used here: http://www.allaboutcircuits.com/vol_3/chpt_1/7.html
It was part of an equation Zin= R1 + (R2 || (Z + R1))
The example shows that 35.14||75.97=24.03, but I couldn't figure out what operation generates that result from those two inputs
A||B = (A^(-1) + B^(-1))^(-1)
A footnote on the page or a reminder about Thevenin analysis might help future readers.
