The opposite of absolute value is essentially the notion of the original signed value of a number. Absolute value measures the distance of a number from zero on a number line, regardless of the direction. It is always a non-negative number. For example, the absolute value of -5 and +5 is 5.
When discussing the ‘opposite’ in this context, it may refer to the idea of considering both positive and negative representations of numbers. If you have a positive number, its opposite would be its negative counterpart and vice versa. Therefore, if x is the absolute value of a number, the opposite can be represented as either +x or -x.
In summary, while absolute value gives you a non-negative measure, thinking of the opposite involves considering the signs and whether the number exists in its positive or negative form.
