Use sliders to set the input voltages of the amplifier (Vp and Vn) as well as Ao, the gain of the amplifier.

Vp=+2

Vp=-2
Vn=+2

Vn=-2

The gain of the amplifier is Ao = .       10-1 106

The voltage at the non-inverting (positive) input is Vp = Volts.
The voltage at the inverting (negative) input is Vn = Volts.
The output voltage is calculated as $Vo = Ao \cdot \left( Vp - Vn \right)$ = Volts.
