Playing with arithmetic can lead us to unexpected and profound discoveries that point toward deeper mathematics and sometimes even deeper science. We solved our last Insights puzzle by performing some ...

In the April Insights puzzle, I tried to guide readers down a path that might be best described as “experimental mathematics.” The goal was to rediscover two constants by iterating simple arithmetic ...

Now, I taught junior high school math for three years, so when I saw this simple equation, I knew I could solve it quickly and I did just that. Before you see my answer, go ahead and solve it for ...
