Here’s another in an intermittent series of posts on articles I found interesting; this one focuses on issues related to wealth, politics, and how they interact in various ways. “Democracy and the ......

Elementary school students learn that multiplication is just repeated addition, and they also learn that multiplication is commutative, e.g., that 4 times 3 is the same as 3 times 4. But if you look at an equation like 3 + 3 + 3 + 3 = 4 + 4 + 4 then it’s not necessarily immediately obvious that the left-hand side (4 times 3) is the same as the right-hand side (3 times 4). It’s even less obvious that this would also be true when multiplying any two positive integers (i.e., 1, 2, 3, …) by doing repeated addition. For example, consider multiplying 137 by 229 by adding 137 together 229 times, and then adding 229 together 137 times.Here mathematician Timothy Gowers addresses this question and outlines some proofs, one of them based on the “multiplication as repeated addition” idea. If I ever have time I might simplify this a bit for consumption by the parents of the elementary school students mentioned above; it nicely illustrates the use of induction and the use of the “successor” idea (formalization of “plus one”) to building up the natural numbers.

Howard County, Maryland resident and blogger, sales engineer for network automation, information security, and other enterprise software and hardware products
Introduction
I live in the Baltimore MD/Washington DC corridor. I blog on a variety of semi-random topics that I happen to be interested in; past and present topics include Howard County, Maryland (where I live), politics (after a fashion), (re)learning mathematics, Mozilla and open source, life as an eMusic subscriber and my thoughts about music and the music business in general. Current interests include issues of wealth and inequality, personal genomics, libertarian political philosophy (as a friendly skeptic), and how this all plays out over the next hundred years.
