The 20 Websites You Need to Learn Math Step by Step

Shay Meinecke 09-10-2015

Learning math online for free can seem too good to be true. But it’s not. There are plenty of resources and plenty of sites that can teach you the necessary skills.


Your age doesn’t matter. Your educational background is redundant. Whatever mathematical goals you have, you can accomplish them!

What seems daunting is finding the right sites for each level of math. One site might be great at teaching calculus but horrible at teaching algebra. Another site might focus on higher level math and completely overlook the lower levels.


The well known Khan Academy is a gold bookmark, but there are other sites out there worthy of your attention. This list promises to compile the best sites for each level so that you can learn systematically, gain a better grasp of math one level at a time, and have fun!

Starting with Arithmetic

Arthmetic shouldn’t be overlooked, as there is always a new and more efficient way at looking at numbers. It doesn’t matter what your age, your brain can always make use of a little math homework Fun With Numbers: 6 Best Single-Player Games For Mental Math You'll need math, logic or a combination of the two to make it through these. And be warned, they are crazy addictive. Read More .



The best site to learn arithmetic should be one that includes easy to follow instructions, shows more images rather than text, and lets the user practice with numbers. I’ve skipped any site that focuses a lot on theory and history, as I believe it is more important to practice with numbers rather than reading about numbers.

MathABC is the best site to practice arithmetic. The site has colorful graphics, is fun and informative, but doesn’t lean heavily on explanations.

No matter what age or level you’re at, you should give MathABC a try!


Other suggested sites include: and Arithmetic Game, which provides an online speed drill.

On to Pre-Algebra

Next up is pre-algebra, a necessary math level for anyone in high school or getting ready to take the GED. Again, no matter what level or how old you are, learning math is always great practice for your brain!

Learning pre-algebra should also be fun and informative but at this level theory and information should start to appear. Though, I think it is also necessary to get plenty of practice.


Math Goodies is the best site to learn pre-algebra, as the site focuses on theory and information, but also provides educational exercises immediately following the lesson.

Other sites include: Cool Math and Math Tutor DVD, which includes a nice set of online quizzes.

Up Next, Algebra 1 and 2

Algebra is no joke, and is often mentioned as the basis or “gatekeeper” for all the other levels, and is also considered a must if you want to comprehend other levels.

At this stage it is important to get a firm grip on theory, while at the same time practicing as much as possible. Graphics and pictures can be thrown out the window as they might be intrusive. Clean and straight-to-the-point text is what matters.


Math Planet does a great job at presenting example math problems and provides an instructional YouTube video at the end of every lesson for further explanation. Additionally, you can take your knowledge and put it to practice on the SAT and ACT section of the site.

You will need to download the SAT and ACT files to see if you answered correctly!

IXL Learning is another great site to review and practice algebra. Check out the Algebra 1 and Algebra 2 sections.

Go with Geometry

After algebra the next step in the right direction towards learning math can be geometry. There are some that say geometry, which is the study of shapes, should be taken before algebra 2, but the order is entirely up to you.

What matters at this stage is plenty of practice and a good grasp of theory. You can get both with a few sites, but the site that really stands out from the others is Math Warehouse.

The site does a great job of bringing together explanations, graphics, and explanation videos. You can even use their online calculator for better practice.

IXL’s Geometry page is great. You can learn even more with Class Zone, a site which promises to improve your test-taking skills.

Turning to Trigonometry

Trigonometry is usually taken after geometry, as it deals with the measurement of sides and angles of triangles. Throw in 3-dimensional figures and it gets more interesting. It is used across all sciences like physics, engineering, and chemistry.

Blackboard and man

The best way to learn anything in math is to know how to get to an answer. The best way of doing that is to practice, and while this site has only a few examples, Dave’s Short Trig Course does an excellent job at presenting trigonometry in easy-to-follow explanations and graphics.

Varsity Tutor provides fine practice tests for any aged learner, and Brilliant is also laid out nicely for easy clarification. Practice to your heart’s content!

Concentrating on Calculus

Calculus, which is the study of of change through mathematics, is best learned through a thorough understanding of theory. A great way to get this type of understanding is to clearly see what you’re learning, and then to be able to put your theory to practice. And although calculus should be broken up, between derivation and linear for example, Free Math Help does a great job of presenting each lesson as its own.

The site brings together theory, examples, three calculus calculators (a derivative, integral, and limit calculator), and even an interactive problem solver, which is quite useful for some problems.

Smart math man

Everything is clearly shown and laid out on the free site. Check it out!

17Calculus is an excellent site for college level calculus. Learnerator also provides a great amount of practice questions for you to review.


A most useful level of math is statistics, or the science of collecting and analyzing numbers and data.

Statistics is mentioned last in this math guide because it is usually taken by seniors in college as a final math course. Though this isn’t always true, it is often the case.

After combing the web for the best statistic course or site, I found a Statistics 101 YouTube channel that really does a great job at explaining stats. You don’t even need to have a great mathematical background to understand what is being taught.

The videos are an average of around 25 minutes long and use graphics and examples to explain statistics.

You can learn more about statistics with Stat Trek, a comprehensive site that includes a practice test and online tools such as a probability calculator.

The Best Thing About Math

Let’s end with the twentieth site that goes back to the History of Math. It won’t teach you any level of math, but a look at the evolution helps place everything in context.

By now your interest should have peaked. Social places like Mathematics Stack Exchange and Reddit have strong math communities. There is also a super-useful list of math websites you should explore further.

No matter what people tell you, math can be used in many situations in your everyday life, no matter what your level or age. You can use geometry with your DIY carpentry projects, statistics to help you understand popular studies, algebra to help you make better tax decisions, and a culmination of all of it to just have fun with numbers!

    I am so terrible at math! I just couldn't wrap my mind around it in high school and had really bad teachers. That being said, I have learned what I have needed to get through my university courses as a mature student and my career...memorized formulas that required you to solve for X. I also got by in my Statistics course (many years ago) but have no recall of how and I need to re-learn and upgrade my statistics so that I can get into and through a Master's program I have my eye on. More than that, I annoys me that I don't have a better understanding of math for this purpose. I don't know if I should start from the basics of arithmetic's you suggested in this article and follow the order you laid out or what? What foundation(s) of math should I learn so that I'll have an easier time with statics and what areas should I skip (for instance, do I need to learn geometry and trigonometry)?

    some great sites, thanks. Your point about practice is dead right though. doing excercises from a textbook will always help me more than just reading or watching videos.

    "your interest should have peaked?" is this that you've been satiated or that our interest has been piqued?

      Khan Academy offers both.

      I decided to work my way up from Khan's1st grade "mission" (I'm up to 6th grade). The structure is nice - you skip around so it doesn't feel like a classroom grind. The short videos do a good job of explaining concepts. I'm learning things I long ago forgot (rhombus?) and practicing rusty, creaking skills. It is a bit gamified but I still recommend it.

    I am really inspired by Barbara Oakley's book (A Mind for Numbers). I have put (re)learning math on my bucket list. I wasn't really good at it in school. It was a bobe-chilling fear of differential equations.

      I'll have to find that book. Thanks for mentioning it

      I wrote this article because I've also wanted to get back into learning math but haven't yet done it.
