The fact is that Google loves numbers:

Google is named after a Googol, which is a 1 followed by 100 zeros. They didn't use the original spelling because someone made a mistake, which was fortuitous since googol.com was taken, but google.com was available.

Google's buildings are numbered 0, 1, e, pi, and phi; all of which have mathematical significance.

Google's first IPO raised $2,718,281,828, which is the product of "e" and $1 billion, where "e" is the base of the natural logarithm.

For their second public offering Google will sell 14,159,265 shares, which is the first 8 digits after the decimal point in pi (3.14159265)

How did they decide which colors to pick for the logo? Just a random pick?

D Rail put up this crap math question, I spent fifteen minutes pondering it, and then, with the correct answer and an explanation as to why (it was 900, btw) I hit "answer this question" only to find he had removed it.

So now my question is EXACTLY how annoying is D Rail.

I'll start. D Rail is as annoying as proudly finishing a math probelm only to have the teacher tell you that he doesn't give a flying fork what your answer is.

Anyone else?

I want to get an estimate of how much I need to save for gas each month. I'll be driving 80 miles a week, for a total of about 320 miles a month. Let's round up and have gas prices be $3.00 per gallon. I drive a 1996 Honda. Let's say that I'll drive on average, at 45 miles per hour.

I just need an ESTIMATE of how much I'll need to spend on gas.

Thanx to someone answering my earlier question i know how to do expand. At least i think. Is this long assed answer correct? (a+b)^14=a^14+14a^13b+101a^12b^2+414a^11b^3+1101a^10b^4+2103a^9b^5+3053a^8b^6+3452a^7b^7+3053a^6b^8+2103a^5b^9+1101a^4b^10
+414a^3b^11+101a^2b^12+14ab^13+b^14
Next question.... I think i understand this correct me if wrong: (2x+y)^4=2x^4+8x^3y+12x^2y^2+8xy^3+y^4 I don't think it is 2x^4+8x^3y+12x^2y^2+8xy^3+2y^4 but if it is tell me. Please grade me -0=2:2, -1=1:2,
-2=0:2. If i got any wrong please tell me what i did?

A rectangular room measures 30 feet in length and 12 feet in height, and the ends are 12 feet in width. A spider, rests at a point one foot down from the ceiling at the middle of one end. A fly (food of food to the former) is located one foot up from the floor at the middle of the other end.
The OLD problem, as above, published in various math challenge books, and I see repeated here, as it probably will be again and again years from now, is to find the minimum distance between the spider and the fly, accomplished by "unfolding" the room and computing the pythagorean distance.
What will would probably be MUCH more of a challenge is to determine if the spider CONTINUES on the same direction, (an after dinner walk? :-) ), straight with respect to the "unfolding" of the walls, until (and if?) it EVER returns to its starting position, and if so, how far does the spider travel. Is there an analytic way to do this (preferred), or as an initial answer one could write a computr program?

100 people have been assigned seats for a lecture. There are exactly 100 seats in the room. However, the first person to enter the room has lost his seat assignment and randomly chooses a chair to sit in. The rest of the 99 people walk in one at a time and sit in their assigned seat if possible, or if someone is already in their seat they randomly choose one of the empty ones.

What is the probability that the last person to enter to room will sit in his assigned seat? And what is the answer if there are 1000 people and 1000 seats?
