Quite literally the worse professor I've ever had. He lectures about things that aren't related to the quiz and homework, he teaches and expects you to learn laws of math that don't actually exist (Associative Law for Subtraction and Balance Numbers), and his office hours are worse than the class.

This professor is the worst teacher I have ever had EVER. If you want to learn absolutely nothing or learn about the numbers he makes up; for example a "twiddle" then feel free to take his class. Office hours DO NOT help. His homework is out of 50 points and getting a 30% on a test translates into a C, clearly this shows that something is wrong.

He literally came into class one day and taught about a math concept he had in a DREAM. All the homework is pre-outlined in his syllabus so there will always be homework due every class.

Mr Langton is a Math Professor for Math enthusiasts. He is steeped in the topic and knows more than most about the topics. His knowledge is deep, and his exacting nature and sense of humor are informed by his love of math. I learned so much about the fundamental nature of logic in this class, including Godel's incompleteness theorem, truly amazing.

Dr. Langton has a great sense of superiority. He's very picky with his assignments and teaches from a textbook that resembles the ramblings of an author that does not understand their audience. He thinks things are "so simple", and when you ask for help, he will just breeze through explanations without really making sense of it.

Langton is the most difficult, and worst teaching professor I have had in any math class. He lectures are very difficult to follow.

He makes examples at home, will get lost when copying it to the board, and will stand there for minutes not knowing what's wrong. Sometimes his examples are wrong and he won't know how to fix it. Assigns homework before explaining it in class. The textbook doesn't help at all. The curve and test corrections are the only saving grace.

Langton can be tough but he's a solid professor and a good guy. Gives a lot of really hard homework, but quizzes and tests are much more manageable and he curves a good amount. You can also get a ton of points back through test corrections. Attendance isn't mandatory, but if you care about your grade, show up to every class and GO TO OFFICE HOURS!!

I believe Dr. Langton cares that his students learn and wants them to. However, there is a major disconnect in teaching style, choice of textbook (ancient and extremely difficult to learn from), and exams that are near-impossible when compared to the hw problems assigned. If taking for higher-level math, expect an extremely difficult time.

No interaction in class at all, office hours are not too helpful either. Hard homework, quizes, exams, but you can make up some points afterwards.
