    Absolute value of a negative number, will give you the same positive number. For example |-4|=4 (because distance on the number line, from -4 to 0 is same as from 4 to 0, -- 4 units)

    like option D for example: \(\large\color{black}{ \displaystyle |–12|,~~~ –|–5|,~~~~ 2, ~~~~|–8| }\) \(\large\color{black}{ \displaystyle 12,~~~ –5,~~~~ 2, ~~~~8 }\) this order is NOT right, because the term |-12| should have been at the very end on the right, not as it is now.

    \(|\)-3\(|\)=3 thus, -\(|\)-3\(|\)=-3

    Yes, so \(\color{red}{-}\)|-3| when you multiply |-3| times -1, is -3. because -|-3| = (-1)•|-3|=(-1)•3=-3

    if it was just |-3| then the order is wrong, because |-3| is ater 0. BUT, -|-3| is same as -3, and it is before zero (but after -7), so it is right

    No, not C, because |-3|=3 so you would have -6, 3, 1, 4
