Proofs in mathematics are what mathematics is all about. They are subject to entire books, created entire theories like Fermat’s last theorem, are hard to understand like currently Mochizuki’s proof of the ABC conjecture, or need computer assistance like the 4-color-theorem. They are sometimes even missing, although everybody believes in the statement like the Riemann hypothesis or ##NP=P##. However, those are exceptions and events at the frontlines of mathematics. The daily mathematical life is cobblestoned by more or less easy deductions and conclusions. Some need detours like rather tricky integrals, a certain substitution or formula to solve them, and some need only modest calculation, or arguments along the line: What if not? The latter is the vast majority since they are required line by line when reading a proof: ##A\Longrightarrow B##. They are also subject to the exercises and problems collected under ‘homework’. This little article will deal with them, i.e. the question...
The purpose of writing a math proof is to provide a logical and rigorous explanation for why a mathematical statement or theorem is true. It is a way to demonstrate that a mathematical statement is valid and can be relied upon in further mathematical reasoning.
The basic structure of a math proof typically includes an introduction, a list of given information or assumptions, a series of logical steps or arguments, and a conclusion. The arguments should be presented in a clear and organized manner, with each step building upon the previous ones to ultimately prove the desired statement.
To ensure clarity and conciseness in a math proof, it is important to use precise and unambiguous language, define all terms and symbols, and avoid unnecessary or repetitive explanations. It is also helpful to break the proof into smaller, manageable steps and use logical connectors to clearly show the relationship between each step.
Some common mistakes to avoid when writing a math proof include assuming what needs to be proven, using circular reasoning, and making unsupported claims. It is also important to avoid using vague or imprecise language, and to carefully check all calculations and equations for errors.
The best way to improve your skills in writing math proofs is to practice regularly and seek feedback from others, such as professors or peers. It is also helpful to read and analyze well-written proofs, and to familiarize yourself with different proof techniques and strategies. Additionally, staying organized and breaking down complex proofs into smaller steps can make the process more manageable.
