                     Paola, Marta, at the following link you can look up, for the upcoming time, a bunch of exercises, just the kind of level you need, about simplifying, extanding, all kind of equations to solve, roots, logarithms, etc. If you have enough time, simply check this link and try to review some of the exercises starting at the bottom of the page and going to the top. You will find all sort of exercises, whose level is about the one you need to work. They are solved and provided with given solutions and explained step by step. If you have any problem just let me know it, anyway we will be working them out as we go furhter within the next lessons.
