Key Concepts

Absolute Value

Absolute value is a measure of the magnitude of a real number without considering its sign. It indicates the distance of a number from zero on the number line, and is always a non-negative quantity. When evaluating an absolute value expression, the expression inside the absolute value symbols is computed first, and then its non-negative magnitude is taken.

Order of Operations

The order of operations is the set of rules that determine the sequence in which parts of a mathematical expression should be evaluated. In expressions that involve absolute value, operations inside the absolute value symbols are performed before applying the absolute value, ensuring the expression is interpreted and simplified correctly.
