This site offers help or practice for students who are taking lower-level undergraduate math classes. This site can be included as a part of lecture or as an extra online tutorial for students.

All online calculators are designed in a way that users can easily use it, and it has a guide with how to write a correct syntax, so users can easily follow directions to write functions or equations and get correct results.  This site offers a great help for students who are taking lower-level undergraduate math classes. This site can be included as a part of lecture or as an extra online tutorial for students.

Some of the explanations are not what US based students or faculty might expect - for example a standard trinomial is factored by using a quadratic equation solver to first determine the roots.

The site offers a large amount of material for the student to explore and practice. The calculators offer solutions with explanations.  The formulas allow a pdf download or the creation of a custom "cheat sheet."  The tests allow topic selection, submission of answers and auto grading and comparison with other test takers.

Both instructor and student can use this site in various math courses in a lecture about one of the topics in the site. Students can easily contact the owner of the site with their questions on one of the topics in the site using the provided email or contact form at the bottom of the site first web page. This site also offers a great collection of various math formulas, lessons, and tests which are very helpful for both instructor and students.

See comment above about unusual explanations.

The interface is in general easy to use and the arrangment of topics should look familiar.

Students and instructors can easily access any of the available calculators with just clicking on the topic of their interest and following all steps need to get the correct results.

As with other separately reviewed pages from this site, ad placement is particularly intrusive and misleading - for example the "download a pdf" buttons that take you to a different site entirely - even though that is a built in feature of some of the formula pages.
