My oscillator only works with the battery backwards?

[Supermario1]

I am using a normal 9v battery connector to power a simple breadboarded 741 IC square wave oscillator circuit. This is my very first circuit, and I immediately noticed that it did not work unless I put the leads on the battery backwards...? This must be some simple silly thing I did, but I would really like some help on this... Thanks!

I guess I must have wired +9v and ground backwards, heh. Terribly stupid of me.

Dude how is that possible? it works with the battery upside down.

you should have connected the positive and negative in reverse way.
so soldering it correctly. Be careful in feature circuit board creation.
