17 no matter if the number is negative or positive, the absolute value of a number is always positive. The answer depends on how far away the number is from zero. So if you ask for the absolute value of -4, the answer is 4 (-4 is 4 away from zero). If you ask for the absolute value of 4 (positive 4, not negative), then the absolute value is STILL 4. it's pretty simple, just remember that the absolute value will always be positive.
That would be -4. The absolute value of -4 is 4, a difference of 8.
the only absolute value would be 4, as the absolute value is the space that the number is away from zero. Both positive and negative four would equal four. On the other hand, if the negative sign was outside the absolute value ( -|4| ), then the number would be negative.
You can think of the absolute value of a number as measuring its distance from zero. 12 is further away than 4 from 0, thus its value is greater.
The absolute value of a complex number a+bi is the square root of (a2+b2). For example, the absolute value of 4+9i is the square root of (42 + 92) which is the square root of 97 which is about 9.8489 (The absolute value of a complex number is not complex.)
