How is total magnification calculated?

Explanation:
Magnification in a microscope comes from two lenses working in sequence, so you multiply their powers. The total magnification equals the magnification of the objective lens times the magnification of the eyepiece. The objective creates the initial enlarged image, and the eyepiece further magnifies that image for your eye. Because these are sequential stages of magnification, multiplication is the correct operation. For example, 40x from the objective with a 10x eyepiece gives 400x total. If you use a higher-power objective, the total magnification increases accordingly. Adding or dividing the magnifications would not reflect how the optics form and enlarge the final image.
