Step-by-step explanation:
one that gives the right conclusion.
Finally, here are extensive discussions of a number of false proofs:
Classic Fallacies
- Philip Spencer, for The University of Toronto Mathematics Network
1 = 2: A Proof using Beginning Algebra
1 = 2: A Proof using Complex Numbers
All People in Canada are the Same Age
A Ladder Will Fall Infinitely Fast when Pulled
Every Natural Number can be Unambiguously Described in Fourteen Words or Less
Of course, these aren't really proofs, because they all have some error in them. What's important about these examples is that they show ways you can make a mistake in using math if you aren't careful enough. When you can understand where the error is, then you can look for the same kinds of errors in your own work, whether it's a proof for school or a calculation you make when you're designing a bridge. (It also explains why mathematicians and scientists don't publish their results without first having others check them to make sure there isn't some subtle error in their calculations.)
