Identify Signs: Identify the signs of the two numbers to determine if they are negative or positive. We have 9 which is positive, and (-7) which is negative. Since they have different signs, we will subtract their absolute values.Subtract Absolute Values: Subtract the absolute values of the numbers. The absolute value of 9 is 9, and the absolute value of (-7) is 7. Subtract the smaller number from the larger number: 9 - 7.Perform Subtraction: Perform the subtraction. Calculate: 9 - 7 = 2.Determine Final Sign: Determine the sign of the final answer. Since the original positive number (9) is larger than the absolute value of the negative number (-7), the result will 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 for 9 + (-7) will be positive 2.

Identify Signs: Identify the signs of the two numbers to determine if they are negative or positive. $\newline$ We have $9$ which is positive, and $(-7)$ which is negative. $\newline$ Since they have different signs, we will subtract their absolute values.
Subtract Absolute Values: Subtract the absolute values of the numbers. $\newline$ The absolute value of $9$ is $9$ , and the absolute value of $(-7)$ is $7$ . $\newline$ Subtract the smaller number from the larger number: $9 - 7$ .
Perform Subtraction: Perform the subtraction. $\newline$ Calculate: $9 - 7 = 2$ .
Determine Final Sign: Determine the sign of the final answer. $\newline$ Since the original positive number $9$ is larger than the absolute value of the negative number $-7$ , the result will 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 for $9 + (-7)$ will be positive $2$ .
