If you have ever been in a biology lab, then you have probably used a microscope to view slides. Microscopes help us magnify tiny objects so that you can view them more easily. This is important when you want to view an object on the cellular level. They come equipped with adjustable settings so that you can view the slides at different powers.

Locate the power of the eye piece, which is usually 10X. It is typically written on the top of the microscope on the eyepiece.
Determine the power of the objective that you are using to examine the slide. Typically viewing powers are 4X, 10X and 40X.
Multiply the viewing power of the eye piece by the power of the objective used to examine the slide. For example, if the viewing power is 10X and you use the power of the objective at 10X, then the magnification is 100X.
