Question

find the absolute value of -15.
|-15| = \boxed{}

Explanation:

Step1: Recall absolute value definition

The absolute value of a number \( x \), denoted \( |x| \), is the distance of \( x \) from 0 on the number line. For a negative number \( -a \) (where \( a>0 \)), \( |-a| = a \).

Step2: Apply the definition to -15

Here, \( a = 15 \), so \( |-15| = 15 \).

Answer:

15
