So I guess you like numbers that are extremely close to pi but aren't pi?

I actually prefer 2pi to pi as 2pi is more fundamental then pi.

I like 5 best.

5 is red, warm and friendly and multiples of 5 benefit from this.
4 and 7 are nice shades of green
6 is black and I don't like it. It took me until 7th grade to learn to deal with it.

I was 9 or 10 yo when I learned that everybody didn't see colored numbers--I laugh now, but that was a scary day.
Until then I sort of felt different from the rest of the kids; that was the day I became sure of it 8^)

5 is purple for me
4 is yellowy-orange. 7 is green.
6 is dark orange/red.

I like Odd numbers especially primes with unusual properties:

or relations to other primes: 2^p +/- p, 5,11 (2^3 -3=5, 2^3 +3=11)

Here is my salute to all who are the quintessence of unrePENTant penta-philia:

Another of my favorites are the first FIVE powers of eleven.
11^0 = 1
11^1 = 11
11^2 = 121
11^3 = 1331
11^4 = 14641
Remember Pascal's Triangle?

skater_chick101, do you live in Indiana by any chance?

Yes I do

Me, too! I've lived here since I was six. Before that, it was Houston. Which part are you in? I'm in the central area!

I was looking at that for a minute and I realised that there is a simple reason for the pattern:

The binomial theorem states that (a + b)^n = Sum from r=0 to n of nCr a^k b^(n-r) - where nCr is n choose r

letting a=10, b=1 you get 11^n = Sum from r=0 to n of nCr 10^r

The reason the pattern fails at 11^5 is that some of the binomial coefficients (entries in that row of pascal's triangle) have two digits.

Pi is my favorite number. Two is my second favorite.

My other favourite number is 66. That's the year that England won the World Cup.
