Taking Discrete Mathematics in August (Help)

[bigk]

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,

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

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!

for reaching out and seeking help! Taking a course like Discrete Mathematics after a long break from math can definitely be intimidating. However, with the right approach and mindset, you can succeed in this course. Here are a few pointers that may help you:

1. Start reviewing early: It's great that you have already ordered the textbook and are planning to review your old Calculus books. This will definitely help you refresh your math skills. I would suggest starting your review as soon as possible so that you have enough time to cover all the necessary topics before the course starts.

2. Seek additional resources: In addition to your textbook, there are many online resources available that can help you with understanding the concepts in Discrete Mathematics. You can also join online study groups or forums where you can discuss difficult topics with other students and get help from experienced mathematicians.

3. Practice, practice, practice: Math is a subject that requires a lot of practice to truly understand and master. Make sure to do as many practice problems as you can. This will not only help you understand the concepts better, but also improve your problem-solving skills.

4. Don't be afraid to ask for help: If you are struggling with a particular topic, don't hesitate to reach out to your professor or classmates for help. They are there to support you and can provide valuable insights and explanations.

5. Stay organized and manage your time effectively: Discrete Mathematics can be a challenging course, so it's important to stay organized and manage your time effectively. Make a study schedule and stick to it, and don't leave everything for the last minute.

Remember, with dedication and hard work, you can overcome any challenges and succeed in this course. Best of luck!
