The low power objective is used first for two reasons: First, focusing the low power objective will insure that the other objectives will be at the proper height. Smashing a slide with an objective can damage the objective. Second, you can see a greater area with the low powered objective. This allows you to easily locate an object of interest, center it in frame and then zoom in on it.
The total magnification is 40x. 10x is the lens in the eyepiece and the 4x is in the lens in the low powered objective lens. You have to multiply it to get 40x. Hope I helped! ^_^ And, ironically, I'm doing my science homework right now.
When using a microscope, you are magnifying the area under the lens by however many times the magnification is on your lens. On low power the area expanded by the lens is smaller than on high magnification. When on low power more is visible and there is less area to search for your given object under the microscope. I recommend finding the object on low magnification, and then switching to high once you have found it.
use the fine adjustment knob to get a better view of what you are looking at.For low power you can use the coarse adjustment and fine adjustmentfor high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.

first view with low power then gradually increase the power. hope it helped you!
