You appear to be on a device with a "narrow" screen width (*i.e.* you are probably on a mobile phone). Due to the nature of the mathematics on this site it is best views in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device (should be able to scroll to see them) and some of the menu items will be cut off due to the narrow screen width.

Here are some links that I've run across over the years that you might find helpful. I try to check them every so often for bad/broken/dead links but I will miss some occasionally so if you should happen to run across a link that doesn't work anymore please contact me me and let me know!

**Math Help Sites**
Here are a several sites that offer help in mathematics. All of these sites offer "live" help. Several of these sites operate through email and other operate through a forum system.

- Question Cove - A new site that can help you with your math courses.
- Math Help Boards A set of forums where you can get help in a variety of math subjects (including both University and lower level subjects).
- Dr. Math Another free help site.
- Study Skills Online This is an excellent web site with some great discussion of study skills by Martin Greenhow. The site has some occasional comments pertaining to the school Dr. Greenhow teaches but is a great site that goes into much greater detail than I do here in my "How To Study Math" section.
- Free Math Help This is a forum in which you can get help in Algebra, Geometry and Calculus. You need to register, but the registration is free.
- S.O.S Math Forum S.O.S Math's forum for getting help for a wide variety of classes. In order to post a question you'll need to register, but it's free.
- Chegg Homework Help Homework help from Chegg.com. They offer help with more than just math!
- StudyPug Math help for a variety of courses.
- Homeworkhelp.com This site has both help services as well as software.

**Online Tutorial Sites**
Here are a variety of sites that have online tutorials and/or lessons. Any tutorial sites listed here similar to mine in that they have online resources but may not necessarily have "live" help as the sites listed above have.

- West Texas A & M Virtual Math Lab This is a nice set of tutorial for all levels of Algebra from Beginning Algebra up to College Algebra.
- Professor Symancyk's Lessons This is a really nice set of Algebra lessons.
- S.O.S Mathematics This site has information about a large variety of topics from Algebra to more advanced math course.
- Math is Fun A nice site with topics ranging from Algebra to Calculus (they even have a little bit of Physics help). They also have a nice selection of games and puzzles to play with.
- Math Warehouse This site has some nice interactive help pages as well as some worksheets.
- Understanding Calculus A nice site covering a variety of Calculus topics.
- Interactive Mathematics This is a really nice site with lots of applets to help with a variety of topics from High School Algebra up to College level Calculus.
- Khan Academy A great site with lots of videos in a wide variety of math subjects. Probably the most well known site of this kind.
- Calc Workshop Another nice site with math videos of lots of different kinds of Calculus problems. Also has some practice exams.
- www.VideoMathTeacher.com The site has over 5000 math videos designed to help students.
- Calculus Expert This is a nice site with videos covering a wide variety of Calculus topics.
- Interactive Real Analysis This is a part of MathCS.org and has some notes on some real analysis topics.
- MathCS.org - Statistics Another section from MathCS.org dealing with statistics.

**Math Information Sites**
Here are a variety of sites that contain a wealth of information about a variety
of math topics.

- Purplemath This site is a great site with lots of resources and links relating to Algebra.
- Basic-Mathematics.com A really nice site with lots of information about Algebra and Geometry with a little Probabilty/Statistics thrown in.
- The Dr. Math FAQ This is a nice site that answers to a lot of the frequently asked questions in math.
- Math World Here is an online
math encyclopedia.
- Cut the Knot! This site contains solutions to quite a few challenging problems including the 12 coins (or bags of gold) problem.
- S.O.S Mathematics This site has information about a large variety of topics from Algebra to more advanced math course.
- Geometric Formulas Here are a variety of geometric formulas from Dr. Math.
- 50 Online Resources for Freshman Here is a nice set of online resources for students (freshman or otherwise...). They even have this site listed!

**Online Exercises and Problems**
Here are some sites that have some excesses for you to practice on.

- EdHelper This site can generate practice problem sets over a wide range of Algebra and Trigonometry topics.
- S.O.S Practice Exams Here
is the S.O.S practice exam page. They have practice exams for topics ranging
from Algebra to Calculus to Differential Equations.

**Software**
Here are are some links to some nice software packages that you may find useful. Some of the software is free and others must be purchased.

- Math 911 This is a nice program for help in Algebra.
- Graphing Calculator This
is a really nice graphing program. It is capable of graphing in 2 or 3 dimensions
and it capable of dealing with all the standard coordinate systems that you're
liable to run across in a calculus course. The only drawback is that it does
cost, but it's much cheaper than other programs with it's graphing capabilities.
- Mathematica This is the program that I used to generate many of the graphs on this site (or at least the base graphs, many of the equations where later added using Photoshop....). This is a very nice program capable of doing pretty much any math you'd like to do. They also sell a student version of the program.
- Wolfram|Alpha This is a really nice web interface to most (maybe all?) of Mathematicas capabilities. It is simple to use and best of all is free which makes it a really nice resource!
- Maple This is another program like Mathematica and is even capable of doing some graduate level mathematics. They also sell a student version.
- Maxima Yet another computer algebra system along the lines of Maple and Mathematica. This is an open source project that arose out of of one of the first computer algebra systems, Macsyma (I actually remember using Macsyma back in the day!) and is free.
- Matlab This is a really nice program for doing numerical computations. It is used in a wide variety of engineering and mathematics applications and is probably one of the most well known/used programs for numerical computations. It is however quite expensive.
- Scilab This is a essentially a Matlab clone. It may not be capable of all the really advanced things that Matlab is, but for most of the everyday applications it is just as capable as Matlab. One of the nice features of Scilab is that it is free.

**Online Calculators**
Here are a variety of online resources that will do some automatic calculations
for you.

- eCalc This is a really nice online calculator that is also capable of dealing with complex numbers.
- QuickMath An online calculator for a variety of Algebra problems.
- Webmath.com This site has will do many types of computations online from Algebra to Calculus. The site will not only give answers but the steps required to get most of the answers.
- Calculator.com This has just about
every kind of basic calculator that you can think of, including most of the
various kinds of conversion calculators that you'd ever need.
- Time Calculators A set of time calculators.

**Miscellaneous**
Just a few sites that don't fit into any of the other areas above.
