Explanation:
Step 1: Determine what absolute value does
According to online, the following is given: "The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line."
Step 2: Determine the absolute value of 15
Since we know that the absolute value gives us the non-negative value of the given number regardless of its sign, we can determine that the absolute value of 15 would just return us 15.
