Identify Signs: Identify the signs of the two numbers to determine if they are negative or positive.−9 is negative, and 5 is positive, so they have different signs.We will need to subtract the smaller absolute value from the larger absolute value.
Determine Operation: Determine whether to add or subtract the absolute values of the numbers.Since −9 and 5 have different signs, we subtract the absolute values.Subtract the absolute value of −9 (which is 9) and the absolute value of 5 (which is 5).
Perform Subtraction: Perform the subtraction of the absolute values.Calculate 9−5.9−5=4
Determine Sign: Determine the sign of the final answer.Since the absolute value of −9 is greater than the absolute value of 5, the final answer will take the sign of the larger absolute value, which is negative.
Combine for Final Answer: Combine the result from Step 3 with the sign determined in Step 4 to get the final answer.The final answer for −9+5 will be negative.−9+5=−4
