What do positive and negative sign of magnification indicate?

Positive would be more magnification, and negative would be less magnification. * * * * * No. M > 1 indicates that the image is bigger than the pre-image (and on the same side of the centre of magnification); 0 < M < 1 indicates that the image is smaller than the pre-image (and on the same side of the centre of magnification); -1 < M < 0 indicates that the image is smaller than the pre-image (and on the opposite side of the centre of magnification); M < -1 indicates that the image is larger than the pre-image (and on the opposite side of the centre of magnification). M = 0 means the image is point-sized and at the centre of magnification. M = 1 means the image coincides with the pre-image. M = -1 means that the image is the same size as the pre-image and on the opposite side.

What is an image in math?
