What is the value of the expression -|-15 + 7|? — ACT

What is the value of the expression $-|-15 + 7|$ ?

-8

To find the value of

-|-15 + 7|

, we first evaluate the expression inside the absolute value bars:

-15 + 7 = -8

. Next, we take the absolute value of that result:

|-8| = 8

. Finally, we apply the negative sign that is outside the absolute value bars, which gives

-8

Evaluate the expression inside the absolute value bars.

-15 + 7 = -8

Before applying the absolute value, the terms inside the vertical bars must be simplified according to the order of operations.

Find the absolute value of the result from Step 1.

|-8| = 8

The absolute value of a number represents its distance from zero on a number line, which is always non-negative.

Apply the negative sign that is outside the absolute value bars.

- (8) = -8

The negative sign outside acts as multiplication by

-1

after the absolute value has been evaluated.
