Compare the size with a rational number. If the absolute value of negative 8 and 0 compare the size, who is bigger and who is smaller?

Compare the size with a rational number. If the absolute value of negative 8 and 0 compare the size, who is bigger and who is smaller?

|-8|=8
therefore
|-8|>0

The rational number with the smallest absolute value is 0. Is that right

Yes, of course

The product of all rational numbers whose absolute value is not greater than 2009 is
Such as the title
Second question
If ab

The first answer must be 0, because as long as there is 0, no matter how many numbers the product is 0;
The answer to the second question is d. There is no way to determine the symbols of a and B. There are no other conditions
