The microscope is a multiple-element system having more than a single lens or mirror. A microscope can be made from two convex lenses. The image formed by the first element becomes the object for the second element. The second element forms its own image, which is the object for the third element, and so on. Ray tracing helps to visualize the image formed.
Recall the way a microscope works. First, the objective produces a magnified real image of the object. Then you look at this primary image with an eyepiece.

Then you look at this primary image with an eyepiece. The overall magnification, then, is the product of the linear magnification produced by the objective and the angular magnification produced by the eyepiece.
