If you mean the difference in terms of numerical value, then it is the positive faction minus the negative faction, which is calculated as the positive fraction plus the absolute value* of the negative fraction - just like the difference between a positive and negative number. * The absolute value of a number is the value of the number ignoring any minus sign; eg abs(-4) = 4 = abs(4). If you mean the difference in terms of where they are on the number line, then the positive fraction is one side of zero (it is greater than zero) and the negative fraction is the other side of zero (it is less than zero).
-6 + abs(-11) = -6 + 11 = 5
abs(n - 6) < 9.
ax + b = 15 or ax + b = -15
That is how the absolute value is defined. For x < 0 the value of x is negative (by definition). Therefore, the value of negative x is positive (negative of a negative). So abs(x) = -x when x < 0

When the second number is positive and has an absolute value that is bigger. Suppose x is the first number and y the second. Then x is smaller than y implies that if x is non-negative then y is larger, and if x is negative then y is less negative (nearer 0), 0 or positive In the first case, abs(x) < abs(y), that is 0 <= x < y In the second case, abs(x) < abs(y) if 0 < -x < y.
Use the function ABS. =ABS(-11) returns the value 11.
The absolute value (ABS) of any negative number is its positive equivalent. Therefore, ABS(-625) = 625.
Use the abs( function. To get to it, press MATH, scroll over to NUM on the top, and choose abs(. Put what is in between the absolute value bars in parenthesis. For example |X+3| would be abs(x+3). Another example: 3|X-2| + 5 would be 3abs(X-2)+5.

if value means a constant that doesn't contain a perfect square as in abs(sqrt(2x)) vs abs(sqrt(2))abs(sqrt(x)) then the former is better, but if theres an extractable perfect square then 2*abs(sqrt(3x)) is preferred to abs(2*sqrt(3x)) or abs(sqrt(12x)).
ABS returns the absolute value, so you use it any time you want to view or calculate with the absolute value.
