e-day!

Ulaanbaatar, Mongolia

Today we celebrated "e-day" in math class, albeit three days late. Last fall my students struggled along with natural logs, and I thought it appropriate that we celebrate e-day with a nice chocolate cake.

e, in case you don't know is "Euler's number" and the number (truncated to 5 digits) is 2.71828. It's one of those math numbers (like π) with magical properties. I'll let you figure out why I chose February 7 to celebrate this math star.
