What is -Vee in transistor amplifier circuits?

[Bassalisk]

I have a quick question.

I can't find anywhere the answer in my textbook. What is this -Vee in attached image? And how do you equivalent that?

And it says here in given parameters that -Vee=-12 V, isn't that +12 V?

Vee is the emitter bias voltage, and Vcc is the collector bias voltage. Looks like they are running this circuit between +/-12V.
