    Angry absolute value

    If |x| < 2 =
    -2 < x < 2
    then,
    |x| > 2 = ?

    Re: absolute value

    Or to put it in another way, if you know that |x| ≤ 2 means -2 ≤ x ≤ 2, then |x| > 2 must mean all (real values) for which |x| ≤ 2 does not hold, so... You could draw a (real) number line to see this better.
