Solves for physics lense problems 

This programs solves for both one and two lenses
Just input what it asks for and it will give you the Di(distance of image), magnification, and tell you if it is real or virtual, erect or inverted
Just make sure you put in a negative focus if the lense is diverging (the lense that is curving in)

This is a very easy to use program and very self explanatory but if you have any questions about it or have any questions about basic programming i'll try to help you.
