I'm starting to learn how to write proofs, and I am wondering how to become fluent in proofs. Is it necessary to do problems that are IMO/Putnam? Can anyone give me some advice?
Thanks in advance.
Thanks in advance.

IKonquer said:Hi micromass, thanks for the advice. I'm going to be taking abstract algebra next semester and I have had some exposure to the ideas of proof by induction, contradiction, truth tables, and the like in high school. But I've never taken an introduction to proofs class in college. Do you think it is possible to learn straight from Fraleigh's abstract algebra w/o having a formal course on proofs? I think my major problem is when I don't follow proofs or understand each step when books give examples.
IKonquer said:What a coincidence! I actually have both Velleman's book and Abstract Algebra by Pinter. I actually started reading Velleman's book from the beginning and stopped. I didn't really understand the importance of unions, intersections, truth tables, and the whole operation on sets. Could you explain why they are important in mathematics?
Also how should one go about reading an abstract algebra book differently than a calculus book?
- the first reading: read the importants texts, read the statements of the theorems, skip over the calculations. This should be quick reading.
- Work through the entire text. Make sure to understand everything you read (and make sure you understand why they do what they do). If you don't understand it, think about it. If the thinking takes too long, ask here.
- Take a piece of paper and try to write down the proofs and calculations that you've just studied. Only look in the book when you're really stuck. Repeat until you know and understand all the proofs.
- Try to expand on the theory: try to make examples of theorems, try to find counterexamples of when the theorem fails (for example, we require a certain number to be positive in the statement of the theorem? Try to find an example of when the theorem fails when the number is negative), make a mind-map of the chapter.
- Make exercises.
The best way to approach learning math proofs is to start with the fundamentals. Make sure you have a strong understanding of basic concepts and principles in math, such as algebra, geometry, and logic. This will help you build a solid foundation for understanding more complex proofs. Also, practice regularly and break down proofs into smaller steps to make them more manageable.
One way to improve your problem-solving skills for math proofs is to read and analyze different types of proofs. Look for patterns and common techniques used in proofs, and try to apply them to new problems. Also, don't be afraid to ask for help or collaborate with others in solving proofs. This can give you different perspectives and help you think outside the box.
Some common mistakes to avoid when writing math proofs include making assumptions without justification, using incorrect logic or reasoning, and not clearly explaining each step in the proof. It is also important to double check your work and make sure you have not left out any necessary information or made any careless errors.
To make your math proofs more concise and clear, it is important to use precise and concise language, avoid unnecessary steps or explanations, and use symbols and notation effectively. Also, make sure to organize your proof in a logical manner, with each step building upon the previous one.
Some helpful tips for managing time when working on math proofs include breaking the proof into smaller, manageable steps, setting a time limit for each step, and prioritizing the most important parts of the proof. It can also be helpful to practice time management strategies outside of working on proofs, such as setting a timer for completing practice problems or studying for a set amount of time each day.
