BLOCK DIAGRAM OF DIFFERENTIAL AMPLIFIER in multisim with the prameters defined in the figure:

FOUR CHANNEL OSCILLOSCOPE IS USED TO RECORD THE OUTPUT WAVEFORMS

WAVEFORMS

Here we can see that we have three waveforms, the largest waveform is of positive input , the second largest is of negative input and the smallest is of OUTPUT.

The gain as you mentioned can be 10000 by changing values of resistance, but practically net output gain can not be such. As we can not obtain 1KV voltage from 1V, if it were possible we would not have needed generators. The output of opamp is limited to +Vcc and -Vcc

Gain of differential amplifier

if

Then we have

And by changing value of R3 R1 or R4 R2 we can have 10000 gain.
