[HomeBrew] Another LM324 OP Amp question

[Loren Moline WA7SKT]

Hello again,
 
I was wondering that if I required only a negative voltage output if the chip could be supplied with a negative voltage and ground instead of positive.
 
If so would you ground the normal + volts pin and feed the - volts to the normal ground pin?
 
Thanks!
