No. You have it backwards . . . . . the absolute value of a negative number is always a positive number.
The absolute value will always be positive because if you think about it, the absolute value.
That is false. A negative times a negative is always a positive. Since absolute numbers are always positive if you make it negative that is not correct.
Other than for the value 0, there are always two numbers that have the same absolute value: the number and the negative of the number, eg 2 and -2 both have the absolute value 2. There is no negative 0, so there is only the number 0 which has the absolute value 0.
It is false because if it is the absolute value of a negative number, the answer would be higher than the original number. |-9|=9
It is false.
It is true. Look at absolute value as a number's distance from zero, and distance can't be negative. Take, say, -7. -7 is 7 away from 0, so the absolute value of -7 is 7.
Not sure what "this" is, but the conclusion is false.
