Zero is obviously a number, but I get what you're saying - "nothing" is the absence of "something", so zero is a purely conceptual number, as an absence doesn't physically exist; it's an idea.
What you're debating is whether or not zero is a natural number.
I don't think zero is truly a natural number, but should be counted as one for convenience's sake.
this guy gets it/me.
but now I have a new question. when my GPS is on and it's telling me how many miles to drive before the next step, it will sometimes say, "in point five miles, bear right."
do you say 0.5 mile since it's less than a mile, or 0.5 miles because the 5 pluralizes it?
would you say 0.999... mile since 0.999...=1, or would you say 0.999...miles since the 9 is plural?
0.5 miles because the plural form is also used for fractions.
.999 mile because it can't be expressed as a fraction but is still equal to one.
Zero is a mathematical concept used as a placeholder or to symbolize that none of a given quantity exists.
Numbers in general are simply abstract symbols used to describe the world. Negative numbers and imaginary numbers can't even be visualized concretely, but they're still used because they have applications in mathematics. It's kind of like that with zero.
I'd go with the Yahoo mail. It's complete utter shit.
About every week, Yahoo has to add some new feature to mail that makes it even worse. Then a couple of days later, they realize it's stupid so they change it back. Overall, the functionality is still pretty bad. I still prefer the late 90s/early 2000s Yahoo mail.
Bitcoins don't show much sign of ever being accepted as a widespread currency. Also, their use in black market transactions and as an alternate currency make them likely to get shut down by the governments.
I've been playing the clarinet for about seven years, and I'm pretty good at it.
At one point, I tried to "teach" myself how to play the piano. I can play a couple songs, but I can't sightread, so it takes me a while to learn them, and I have trouble playing more than one note at a time.
