The answer depends on your mathematical ability.
Not necessarily, for example: If you subtract 3 from 4, then you get +1. But if you subtract 4 from 3, you get -1. The answer will always be an integer, but you cannot make a general statement about the sign, without knowing more information.
Yes
Sometimes. For example: (-4) - (-3) = -1 (-4) - (-4) = 0 (-4) - (-5) = 1

The number was less than -2, for example - 3,000,000 -3,000,000 -(-2) = -3,000,000 + 2 = -2,999,998

Yes
less than
That has no integer solution. Three times an integer is another integer; if you subtract to integers, you get an integer again, not a fraction.

To subtract a negative number is equivalent to adding a positive number. Two negatives multiplied make a positive.
yes
That is any number that is an integer, and the square of another integer. For example, 4 is the square of 2, while 9 is the square of 3.That is any number that is an integer, and the square of another integer.

You will get a positive integer. If you subtract a negative number, you will be adding it. I think of it like 2 minuses equals a plus. :P
