A)

the left is going down 2 a time, right stays the same. The quotient(i think that's what it's called) is increased by 1 each time. Thus, 

0/-2 = 0

-2/-2 = 1

And you can continue the pattern from here!

B)

Right increase 4, center constant, right decrease 1.

0/-4 = 0

4/-4 = -1

And continue the rest.

Yes, such as the AoPS Mathcounts.

That's true.

Why are you asking the same question over and over again>

Don't repost your question really fast. You just asked it an hour ago.

Yeah, snow. 
 

Rain is water and has surface tension so is not "not together" but snow is technically seperate but gathers on the ground into one.

I have answered this question last month or so.

See if you can find the question in my answers.
