I remember this equation from AP Physics 2. If I recall and get an intuition of the quantity magnification, left/down of lens= negative, right/up of lens = positive. Negative magnification typically means the image is real and that the image is flipped, whereas a positive magnification usually entails a virtual image. A virtual image is one where the light rays don't actually arrive at the location.

@rwang0110 I also remember this from Physics, (Thermo & Optics) nice recall from your explanation.
