Dear Kid,

Happy 11th!

The number 11 is very cool (not necessarily cooler than other numbers, but we’re not talking about other numbers today).

There are all sorts of interesting things about then number 11 that I don’t really understand (including that the number 11 “carries a vibrational frequency of balance.” Say what?) so I’m not going to talk about them. If you want more, you can consult My Friend the Internet your-own-self.

One of the fun facts (excuse me, “easy to understand fun facts”) is that multiplying 11s lets you build Number Eleven Pyramids.

Number Eleven Pyramids
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
Feel free to keep going—it works.

Do you know about elevenses? It’s what you eat around 11am if you happen to be in the UK. If you happen to be in the US, you still eat it but it’s called a coffee break.

The number 11 is important in sports. In football, field hockey, cricket (who knew?), and soccer, there are 11 players on each team. Not in rugby, but they make up for it by having a ball that’s 11 inches long.

There are all kinds of funky tricks for figuring out if a number is divisible by 11. For example, if you add up the odd digits and then add the even digits and take the difference, if the resulting number is a multiple of 11 (including 0), then the original number is divisible by 11. And I repeat, say what? Easier (but perhaps not as interesting) to grab a calculator

Most importantly, the 11th is today. Hope you can find 11 great things about your day.
