No. |m| can only be positive.

Step-by-step explanation:

Absolute value |m| indicates magnitude, i. e. it has no "direction". m=-18 indicates that m is 18 units left (negative) of position 0; it has direction. |m| asks for the value of m without any direction, i. e. its magnitude.

If it was: |m|=18 then the rest would be true.
