What is an example of proof in math? An example of a proof is for the theorem "Suppose that a, b, and n are whole numbers. If n does not divide a times b, then n does not divide a and b." For proof by contrapositive, suppose that n divides a or b. Then n certainly divides a times b, since it divides one of its factors.

Write out the beginning very carefully. Write down the definitions very explicitly, write down the things you are allowed to assume, and write it all down in careful mathematical language. Write out the end very carefully. That is, write down the thing you're trying to prove, in careful mathematical language.

?To prove? in mathematics means to write a proof of a statement in the context of a mathematical theory. A proof will be an "argument" starting from the axioms of the theory and previous proven results and concluding with the statement to be proved that uses logical "correct" deductive steps (i.e. a valid argument).

A proof must always begin with an initial statement of what it is you intend to prove. It should not be phrased as a textbook question (?Prove that?.?); rather, the initial statement should be phrased as a theorem or proposition. It should be self-contained, in that it defines all variables that appear in it.

One way to prove that an equation is true is to start with one side (say, the left-hand side) and to convert it, by a sequence of equality-preserving transformations, into the other side. But remember that a proof must be easy to check, so each step deserves a justification.

Equations are centered on the page and labeled with Arabic numerals, right-aligned, in parentheses, and referred to only by those numbers in the text ? e.g., you should always say ?as seen in (3)? rather than ?as seen in Equation (3)?.

Proofreading Techniques Read your paper aloud. Sometimes writing sounds different in your head than it sounds on paper. Make a list of errors that you commonly make and keep an eye out for them. Read the text backwards. ... Proofread for only one type of error at a time. Double check everything: ... Read slowly and carefully.
