What is the absolute valur of -13?
The absolute value of -13 would be 13. This is used in math.
How do you find the absolute value of a rational number?
Suppose q is a rational number. Then if q >= 0 then abs(q) = q.If q < 0 then abs(q) = -q [which is positive].
Is a set of negative numbers closed under the operation of taking the absolute value?
Well, the negatives would become positives because they're in between the absolute value. (| |). For an example: | 5 - 2 + 13- 3| Would become |5+ -2 + 13 + -3| then if you add them, you get |3 + 10| and 10 + 3 is |13| which becomes 13. So basically, any equation in the absolute value will be positive, unless there's a negative sign on the outside of the symbol. Like this for an example, would be negative: -|5+ 3+10| Add them and you get: -|18| take the absolute value off, and you get a -18.
What is the distance between the numbers -13 and -4?
-9
