Identify Operation and Numbers: Identify the operation and the numbers involved. We are adding -8 and 8.Determine Result Sign: Determine the sign of the result. Since we are adding two numbers with opposite signs, the result will depend on their absolute values. The absolute value of -8 is 8, and the absolute value of 8 is also 8.Add Absolute Values: Add the absolute values. 8 + 8 = 16 However, since one number is negative and the other is positive and they have the same absolute value, they will cancel each other out.Determine Final Result: Determine the final result. Since the numbers are equal and opposite, the result of adding -8 and 8 is 0.
