What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 10x and an ocular lens power of 5x?

The rule is almost always to multiply all numbers that you get. Thus, the answer is 50. That should be easy multiplication for a high school student... hopefully :)
