Play with the distances between the two until the image is clear and now you have a telescope. An important discovery as a single lens of the same power would be difficult to make and heavy to carry.

How does this simplify it any more than just saying they multiply?

Magnification is not a property of the glass alone, it depends both on the glass and the distances. You can choose the magnification based on these distances (three in this case: object to first glass, between glasses, second glass to eye or screen).
