What exactly don't you understand about how do you write a multiplication and division expression? I recall having difficulty with the same thing in Pre Algebra, so I think I could try to give you some advice on how to approach such problems. However if you want help with algebra on a long term basis, then you should get Algebrator, that's what I did in my Intermediate algebra, and I have to say it's so cool! It's much cheaper than a private teacher and you can work with it anytime you want . It's not hard to use it, even if you never ever used a similar software . I would advise you to buy it as soon as you can and forget about getting a math teacher. You won't regret it!
Since the Algebrator is user friendly, any one can get it set up and start using it within minutes. Prior knowledge is not at all essential to work with the Algebrator. Be it rational inequalities, converting decimals or conversion of units, go ahead and type it in the search box that comes up as soon as you open Algebrator. This gives you a select set of output that offer all the required information on the heading of your choice. You can go through the links one by one and completely comprehend the basic principles of College Algebra.
