Favorite Numbers

What’s your favorite number? No really, I’m curious. I’ve been asking students that every semester for eight years now, and I’ve learned quite a bit about people from that simple question. Single digit numbers are incredibly popular. Likely, if you fit in that crowd, you chose your number at such an early age you can’t remember having any other. You are decisive and have not lost your inner child. Unless, perhaps, your number is 7. Seven is the classic response, and is therefore the default choice for someone without a strong feeling for any other number.

Thirteen is nearly as common. If 13 is your number then you like to be different, but not too different. You probably enjoy pushing people’s buttons. The next most common category is dates of the month and then jersey numbers. Usually a date is an anniversary or a child’s birthday. I find these to be most common in women with at most one child. Jersey numbers are common in the 18-25 year old students with a fond recollection for high school athletics.

23 and 42 have their own cult followings, but identifying with numbers like this mainly serves as a shibboleth — connecting members of the same cultural tribe.

So, what about you? What does your favorite number say about you? My generalizations aside, numbers are something that resonate deep within us. Why is that? We live in a society that decries mathematics, but almost everyone you ask has a favorite number. It’s deeper than that, though. Imagine you are sitting in a classroom with 20 other students and I ask the question. What is your response to hearing that Mike’s favorite number is zero. Did you just sigh a little?

What if Mike said his favorite number was π? Did I hear someone mutter “nerd” under their breath? Have you ever met someone with a negative favorite number? Or a fraction? Admit it. Most of us are experiencing numerical prejudice at the thought of it. How is it that numbers elicit a response that visceral? Is it innate, or has the sum of your frustrations and pains in learning mathematics influenced your opinions about something as innocuous as a number?

I don’t know. What is a number anyway? It is possible that they are just tools for measuring and counting. I believe otherwise. I think that numbers are an alphabet to a universal language. That language is mathematics.

  1. 1024, 2048, 4096? Actually, it was quite memorable at a computer science programming competition during college MANY years ago we were traveling to the host city and stopped somewhere to buy snacks. The 6-pack of snickers was $2.56 (2^8) which closely tracks with the binary nature of things and caught my eye! (I think there were 1-2 other binary-related things but it’s been too long to remember precisely)… So after reading AND thinking, I might go with some power of 2 – perhaps even 256 (though before this read I never really had a favorite number to speak of – whatever THAT says about me 😉 If I had to go with a favorite recent number-related saying I’d say “Programming is as easy as 0, 1, 2”!

    • Little Reg is surprised your favorite number isn’t an IP address. I think that the more exposure to numbers we have the harder it is to have a clear favorite. I’m certainly less sure about mine than I was a decade ago.

  2. I’ve never been good at picking favorites of anything. But if I had to choose, I’d probably say 3. No particular reason. I just like it. My bday is the 3rd of Jan, so maybe that has something to do with it. Or perhaps it’s bc of the Holy Trinity. I’ve just always liked 3 more than the other numbers I guess. Haha.

    • I think it’s safe to say you’ve held on to your inner child. Three is an amazing number, though, and I’m glad you have it.
