      Well, I wish you would have given an example of the problems you are studying.
      If I have variables in an equation, I can't do much with them unless they are the same; by that I mean, not much I can do with:      3A - 2B.    If there is a similarity, as in 3A - 2B + 4A, I CAN do something, like add the 3A and 4A (7A), and simplify my equation to 7A - 2B.


      Is this what you mean?

        Measuring 42mm in diameter, the link case is water-resistant to 50m and is made of polished steel or plated in rose gold. It houses the F-392 caliber, an automatic movement running on 4hz, delivering 55 link hours of power reserve when fully link wound, 9 hours more than the previous models.
