WebIn a nutshell, the argument starts with an equation and we simplify until we obtain something we know is true. If this format is valid, we can “prove” that 21 = 6, as follows: 21 = 6 6 = 21 27 = 27 By writing 21 = 6 at the beginning of the proof, what we really say is “ Assume 21 = 6 is true.” But this is what we intend to prove.

WebHere we have 1/2=3 (which is a contradiction in every axiomatic construction of the reals) and 1/2<3. Now take a random statement P, say “The riemann hypothesis is true”. Since the statement (1/2<3) is true, we have that the statement (1/2<3 or P) is true. But since we assume that (1/2=3) is true, (1/2<3) has to be a false statement.

WebA proof is a string of implications and equivalences, where the entire text is the answer. In a regular mathematical problem, you often draw two lines beneath your last expression to show that you have reached a final answer.
