Key Concepts

Order of Operations

When simplifying an expression, operations must be performed in the correct sequence. In this case, the absolute value is calculated first, followed by the application of the negation operator.

Negation

Negation is the operation of taking the opposite sign of a number. When applied, it changes a positive number to negative and vice versa.

Absolute Value

The absolute value of a number is its distance from zero on the number line, which means it is always non-negative. It effectively removes any negative sign that might accompany the number.
