phet Scientific Simulations This is a free site that has scientific simulations for learning math, physics, chemistry, and other science.  The simulations lets you see in a lab format so you can learn principles by observing. Most of these are animated games which may show something like a water filling up a tank or trajectories.  Regarding math there are the following principles: Curve fitting Graphing Area Balancing Fractions Linear regression This is a good way to learn math and is very helpful to show students what is happening as opposed to just seeing formulas. This is appropriate for: Grade school students Middle and junior high students High school students College students 

My Math Forum Post your question and get an answer or if you are like me you can go to the site to answer questions.  This is a pretty decent site to correspond with others on how to solve problems.  This forum has a lot of posts and appears to have a lot of teachers as well as professors.   This is a great site to get your problem solved.    The forum covers these subjects: Arithmetic Algebra Abstract Algebra Geometry Precalculus Trigonometry Real analysis Topology Probability and statistics Linear algebra Calculus This is appropriate for: Math 3 through 6th grade students Middle and Junior high school students High School students College students Professionals Life long learners

Free Math Help Forum Post your question and get an answer or if you are like me you can go to the site to answer questions.  This is a pretty decent site to correspond with others on how to solve problems.  This forum has a lot of posts and a lot of responses to questions.  This is a good site to ask questions and if you like to answer questions this is great too.  There are many problems posted so you may be able to find one that is similar to yours.  The forum covers these subjects: Arithmetic Algebra Geometry Precalculus Trigonometry Probability and statistics Linear lgebra Calculus Advanced math Math Odds and ends This is appropriate for: Math 3 through 6th grade students Middle and Junior high school students High School students College students Professionals Life long learners

Math 10 Math Forum Post your question and get an answer or if you are like me you can go to the site to answer questions.  This is a pretty decent site to correspond with others on how to solve problems.  Besides forums, this site has practice tests and also has problems and solutions.  I did notice that some of the problems go a long time without being solved but there are a large variety of problems and this is a worthy site.  The forum covers these subjects: Algebra Geometry Precalculus Trigonometry Probability and statistics Linear Algebra Calculus Differential equations Physics Computer algorithms This is appropriate for: Math 3 through 6th grade students Middle and Junior high school students High School students College students Professionals Life long learners

Mathway Math Calculator This is a great free calculator that does these types of problems: Basic math Pre-algebra Algebra Trigonometry Precalculus Calculus Statistics Finite math Statistics Linear algebra This has a very nice keyboard for entering the problems and is intuitive.  You type in the equations as you would solve it.     Some harder problems like ∫dx/(x⁶+1) or solving higher order polynomials cant be solved with this calculator but this calculator will do most problems.  This is great for checking answers and will show steps if you sign up on Facebook. This is recommended for: Primary school students Secondary school students College students Adults

Integral-calculator Integral calculator is a good site with a very powerful calculator for integrals.  I like the format of to enter the numbers.  The steps are a bit cumbersome but it is a great site for solving your integrals. This site is appropriate for: High school calculus students College calculus students Professionals

  Symbolab integral calculator Calculator for Integrals and other math problems.  This is definitely a good site to visit especially if you need a graphing calculator and you don't have one.  This site also shows problems worked. This site is appropriate for: Elementary students Secondary students College students Professionals

Exams with Solutions This is an interesting site which gives links to sights with solutions to math problems.  Many of the links just post sample tests.  These are teacher sites, mostly from universities that students often use to help them study for tests. I did find some broken links and also most of the links are to just exams but there are exams that do have solutions.  Most of the site is a little more advanced and directed towards college students but it would also be appropriate for secondary students looking for study material for their exams. The subjects covered: Biology Chemistry Mathematics Physics Economics Computer science Engineering  Statistics This is appropriate for: High school students College students Self learners

Wolfram Alpha This is one of my favorite sites.   I often refer my students to this service.  This site  has both a free and paid services. The free service is adequate for most calculations.  When you enter a function: It will give a graph of the function.   For instance lets say you enter xsinx and it will graph the function.  This will give you a graph for just about any function that you enter.  This is a graphing calculator. The calculator will give you the domain and range of the function. This will give you a series representation of the function. This will give you an improper integral of most functions if the derivative exists. This will give you a derivative of most functions if the derivative exists. This will find the maxima and minima of the function. This will give you and alternate function.
