That's definately what I'm trying to figure out. I understand the answer to the second question.
On the first question, if IN-=-1, IN+=2, and the Gain=4. then the output is -1 *-1 (due to IN-) + 2 (IN+) for a total of 3, then apply the gain of 4 for Vout=12. If I'm reading your response correctly, this is correct and the other option (below) is not.
Which is opposed to the other option, 2 *4 for a toal of 8 and then apply the IN- of -1 for an output of 9. So Vout=9 is not correct.
Thank you for you time and help. It's been a long time since I've had to work at this level and I'm now realizing how rusty I am.
