Step 1: Understand what the absolute value means. The absolute value of a number is its distance from zero on the number line, without considering direction.
Step 2: Calculate the absolute value of -8. Since -8 is 8 units away from zero, |−8| = 8.
Step 3: Calculate the absolute value of -3. Since -3 is 3 units away from zero, |−3| = 3.
Step 4: Add the two absolute values together. So, 8 + 3 = 11.
