(1) The absolute value of the number a is the distance from the point representing the number a on the number axis to the origin (2) The minimum absolute value is 0. (3) If the absolute value of A is greater than that of B, then A must be greater than B. (4) If the absolute value of a is equal to a, then a must be a positive number.
