Rated 5 out of 5 by from Fantastic! This is really an amazing course; awesome and wonderful! Everyone should be exposed to the marvels of mathematical visualization from an early age. I enjoyed the class a great deal. Professor Tanton makes the class very enjoyable and engaging.

Rated 5 out of 5 by from Unique, Insightful Visualizing math interests me. Initially this course seemed a little too basic, but that changed fast. By lecture four I was hooked and it became a satisfying challenge to complete all 24 lectures. Prof. Tanton is a lot of fun and he blast his way into what, seemed to me, quiet complex math. I loved the dots and boxes, his approach to “place” and to binary were particularly helpful. His explanations of various infinites and random walks, to name a few, were also great. The course was not actually easy to get thru, which I like, as long I “get’ something. I had particular trouble with two of the lectures including the last (he was going fast). But watching several times and pausing a lot for note taking helped and L24 is amazing, with the division of jelly beans into a .001 (base 2) size pile. I recommend the course highly for Math strivers who enjoy a challenge.

Rated 5 out of 5 by from excellent visuals This is a great course. As someone who was uncertain as to why my teachers taught me the addition/subtraction/multiplication/division algorithms that they did, I love Dr. Tanton's visual work and presentations. I wonder how/whether I can share this course with my 7th grader without undermining her math teacher's efforts.

Rated 5 out of 5 by from Mind-blowing, educational, and fun! Professor Tanton makes each lecture a joy to follow. He treats simple and complex mathematical problems as if they were puzzles. Through numerous illustrations and demos he identifies patterns and derives solutions. Then he uses those illustrations to prove why the technique he used works. He starts with simple arithmetic and numerical bases, then moves onto algebra and geometry, probability theory, quadratic equations, and beyond. He spends several amazing lectures demonstrating the many patterns inherent in Pascal's triangle and the Fibonacci number sequence. I wish I had been taught some of these techniques when I was learning math in elementary school through high school. Some of these methods are much easier to work with than the cryptic formulas we were forced to memorize. I enjoyed this course so much that I may repeat it. The instructor clearly is having fun in each lesson. Highly recommended!!!

Rated 5 out of 5 by from Prof gives enjoyable presentation I bought a used copy for myself, a new copy for my great gandkids and my grandson used the library copy. We all are enjoying the presentation. They are in high school and college so it gives them new ways to look at Math.

Rated 5 out of 5 by from Outstanding! Dr. Tanton does an amazing job at explaining and more importantly showing us several key topics of moderate-to-advance math. My 11 year old son who is pretty good at math for his age but doesn’t necessarily go in search of more math to do, has joined me for of these lectures on his own - with no pressure applied by me. When I asked him what kept him interested in the lecture, he told me that he thought that some of the math was challenging at first until Dr. Tanton explained it in visual terms which he enjoyed. I strongly recommend this course - especially if you have a teenager or younger student that you want to present math to in a different form where equations and memorization is not the goal. Some of the math is advance so I recommend that the viewer select areas they are more familiar with so that the visual aspects can be better appreciated. Enjoy!

Rated 5 out of 5 by from A Light At The End of the Tunnel! I grew up with a maths teacher that was the same from first through twelfth grade! I never "got it" because she was rather obtuse and you never, ever questioned her...for any reason! Why..I would ask? "Because I SAID SO!" Needless to say I did not enjoy my math classes. But with my biology and chemistry teachers I understood the problems? Was it the teacher? Yes... and now at 70 I have found the teacher I wish that I would have had way back then. He makes the subject interesting, he makes it fun! and isn't that what learning should be? This is a thoroughly enjoyable course and I highly recommend it...whether you grew up mathematically challenged or not!

Rated 5 out of 5 by from Great Insights This is the second Professor Tanton course I have watched. The other was Geometry and was equally entertaining. Professor Tanton is one of my favorite mathematics professors along with Professor Edwards and Professor Benjamin. He is very easy to follow and has a warm and personable style. Although this may appear to be an elementary course based upon the lesson titles, the teachings are innovative. His ideas on exploding dots and division of polynomials are fresh and amazing. I have never seen a better explanation of Pascal's Triangle. If every professor was as engaging and creative as Professor Tanton, no one would hate math.
