25 divided by 5 is 14
Neal points us to a very clever video in which the preceding "fact" -- that 25 divided by 5 is 14 -- is proven in three different ways: long division, multiplication, and addition. I like this kind of "proof" and try to collect as many as I can.
I am a graduate student, working on my PhD in math. I do research and teach calculus to college students. In my free time, I work on becoming an elite distance runner. This blog contains my reflections on math and running, including race writeups.
