1. ## What's your Pet Number?

What do you mean, you don't have a Pet Number? How can one not...?

Sum of the numbers 1 to 10.

Sum of the squares of the numbers 1 to 5.

The product of two primes.

The difference between two squared numbers.

Squared = 3,025; 30+25 = 55.

The atomic number of cesium, the basis for accurate time keeping.

In my version of sign language, what holding up both hands means.

It's a Fibonacci number--the sequence which goes 1,1,2,3,5,8,13,21,34,55,89...

2. 55: It's the speed limit of the road I was driving 10 mph over and got a ticket two weeks ago
