1)www.Mathway.com
I really liked this website because it basically solves any questions you have. All you simply have to do is input any equation, and you'll get the answer plus the steps to solving it. Also, the fact that you can check your math format (in case you make any mistakes) is very useful. Unfortunately, this website doesn't solve word problems. Another thing that is slightly annoying about this website is that it is difficult to figure out at first. However, once you get the hang of it, it becomes quite simple, and actually very efficient. Finally, the site doesn't load very fast. This is reasonable due to the huge amount of information it needs to store and process, but nevertheless, it could get annoying if one is solving multiple problems. One particular part I liked about this site is addition of the glossary. It gives you a list of all the different math terms in case you're confused or unsure about one.
This website solved the "Completing the Square" problems very similar to how we learned in class - except for a few deviations, it was identical. When "Completing the Square," the answer is not left in the standard “y=a(x-p)+q” form, although it does explain the process very clearly. Since the site can only solve equations, it is of no use in figuring out maximizing and minimizing problems. Lastly, the website figured out the inverse questions easily and the same way in class, but instead of switching the X and Y variables, the method is to solve for X. Personally, I prefer to switch the X and Y Variables, finding this method much simpler.

First off, this website is visually appealing, with a simple yet functional layout. The website is categorized very neatly, and it is easy and simple to find what subject you want help on. Once you click on a subject, there is a detailed explanation with simple, hard and weird cases. The hard and weird cases are especially helpful, explaining to you how simple these seemingly complicated questions are. For example, in “Solving quadratic equations by factoring”, there different examples of quadratics that contain powers such as 4 and 2. Likewise, the site explains Completing Squares very thoroughly, showing how to add terms in to complete the perfect square. I particularly like the fact that the explanations are sophisticated enough to explain clearly, yet at the same time simple enough so that the average person can understand. On this site there is also a list of links which lead to other helpful sites, which is a big plus in case the problem you have can’t be solved. Also interesting, is the "Why do I need Math" page. In here, is a whole list of reasons why math isn't as useless as most students think. In general, there really is no cons to this site.
