Identify Signs: Identify the signs of the two numbers to determine if they are negative or positive. We have -4 (negative) and +8 (positive). Since they have different signs, we will subtract the smaller absolute value from the larger one.Determine Absolute Values: Determine the absolute values of the numbers and subtract the smaller from the larger. The absolute value of -4 is 4, and the absolute value of 8 is 8. Subtract the smaller absolute value from the larger one: 8 - 4.Perform Subtraction: Perform the subtraction to find the difference. Calculate: 8 - 4 = 4.Determine Sign: Determine the sign of the final answer. Since the original number with the larger absolute value was positive (+8), the result will also be positive.Combine for Final Answer: Combine the result from Step 3 with the sign from Step 4 to get the final answer. The final answer is positive 4.

Identify Signs: Identify the signs of the two numbers to determine if they are negative or positive. $\newline$ We have $-4$ (negative) and $+8$ (positive). $\newline$ Since they have different signs, we will subtract the smaller absolute value from the larger one.
Determine Absolute Values: Determine the absolute values of the numbers and subtract the smaller from the larger. $\newline$ The absolute value of $-4$ is $4$ , and the absolute value of $8$ is $8$ . $\newline$ Subtract the smaller absolute value from the larger one: $8 - 4$ .
Perform Subtraction: Perform the subtraction to find the difference. $\newline$ Calculate: $8 - 4 = 4$ .
Determine Sign: Determine the sign of the final answer. $\newline$ Since the original number with the larger absolute value was positive ( $+8$ ), the result will also be positive.
Combine for Final Answer: Combine the result from Step $3$ with the sign from Step $4$ to get the final answer. $\newline$ The final answer is positive $4$ .
