Here’s an easy one: 1+2-(3-4-5)*6*7*8-9

How about 1*(2+(3-4*(5/6-7))*8)*9

Or maybe 1+2345*6/7+8-9

Or (1-(23+4)*5)*(6/(7-8)-9

Maybe .1+23*(45+6*7)+8+.9

Even 1-(.2+(3+.4)*(5+67))*(.8-9)

If you love numbers and are excited about 2010, you’ll get a kick out of the cool 2010 page by Nadav Samet (surprise – he works for Google.)  (Thanks SMoody!)

I love numbers.  I was thinking about numbers and dates on my run yesterday.  Here’s a few fun ones for you.

101010 – On 10/10/2010 the answer the life, the universe, and everything will be revealed.

030309 – Isn’t it fun to have square root day be “prime square root day”?  How many of them are there in the 21st century?  How about 02/02/04, 03/03/09, 05/05/25, 07/07/49.  That would be five.  So there are a prime number of prime square root days.

090909 – Number 9, Number 9, Number 9 is the day that the Beatles version of Rock Band is released.  As a special bonus it’s the second day of my Q3 off the grid vacation.

Got any other good ones for me?

There are so many reasons to love Valentine’s Day.  My favorite is that on 2/14/09 the Unix Time will be 1234567890.  This happens at exactly 00:31:30 CET.  Yeah – it’s a little bit of a cheat since CET = GMT+1 and – correspondingly – it will still be 2/13/09 in the United States.  Just another good reason to go to Paris for Valentine’s Day.  (Thanks ScottM).

Yes – those are the lyrics – buried at about 2:05.  Who said mathematicians don’t know how to rock.

Thanks Ryan.  Cornell just went up a notch in my book.

Exactly 20,000 miles.  What numerical fun!
