Help with Coordinates

Hello,
In GL, if up me is Y+, down me is Y-, in my right is X+ and in my left is X-, in my front I have Z+ of Z-?

Thanks

I suppose that then the positive z-axis is point out of the monitor. (you look into the negative z-axis).

Maybe this figure from the OpenGL Super Bible helps:

Hope this helps,
