Taking Discrete Mathematics in August (Help)

Click For Summary

Discussion Overview

The discussion centers around preparing for a Discrete Mathematics course, particularly for someone returning to mathematics after a significant gap. Participants share their experiences and suggest study strategies, focusing on the content and skills relevant to discrete mathematics.

Discussion Character

  • Homework-related, Conceptual clarification

Main Points Raised

  • One participant expresses intimidation about returning to mathematics after five years and seeks advice on preparation.
  • Another participant suggests that reviewing calculus may not be beneficial, recommending instead a focus on algebra and proof techniques.
  • A third participant notes that a proper discrete math course typically starts with logic and truth values, emphasizing the importance of reasoning skills over calculus knowledge.
  • Participants agree that discrete mathematics involves different types of reasoning and problem-solving compared to traditional calculus courses.

Areas of Agreement / Disagreement

There is a general agreement that discrete mathematics does not heavily rely on calculus, but rather focuses on logic and reasoning. However, specific study strategies and the importance of different mathematical foundations are discussed without a clear consensus on the best approach.

Contextual Notes

Participants mention varying experiences with discrete mathematics courses, indicating that the content and focus may differ across different curricula. There is also an acknowledgment of the need for foundational skills in algebra and logic, but no specific consensus on the most effective review methods.

Who May Find This Useful

Individuals preparing for a Discrete Mathematics course, especially those returning to mathematics after a break, may find the shared experiences and suggestions relevant.

Hi all,

I am going to be taking Discrete Mathematics in August and my last Math course was about 5 years ago. I am a little intimidated to just 'jump' back into Math especially a course like this one.

Can anyone who was successful give me a few pointers? I ordered the Textbook and will start reviewing, I am also looking in my old Calculus books just to sharpen my mind some.

Thanks

Hi bigk, :smile:

In my opinion, reviewing calculus will be useless here, since discrete mathematics doesn't really use much calculus. Instead, review some algebra and review proofs (if your discrete math was like mine, then you'll encounter many proofs!).

The good thing about discrete mathematics is that it's very unlike other math classes. You won't be calculating derivatives and integrals, but you'll be reasoning a lot. Reviewing your new textbook should really help you. And don't forget posting any questions you have here on PF :smile:
 
A proper discrete math course should begin with a discussion of logic, what it means for something to be a statement and what it means for a statement to have a truth value. You'll have fun drawing truth tables.

In fact, thinking back on my discrete class, we did not utilize any knowledge from Calculus until the very end of the course. Most of the material required being comfortable with algebra and the possession of an ability to think rationally and spatially.
 
Thank you for the input! I will definitely be coming to physics forums for my questions. In the past I would usually just search and find my relevant question.

I guess I will start with reviewing all of my Algebra and begin to think more rationally! :approve:
