Identify Signs: Identify the signs of the two numbers to determine if they are negative or positive. We have 7 which is positive, and -7 which is negative. Since one number is positive and the other is negative, we will be effectively subtracting their absolute values.Determine Operation: Determine whether to add or subtract the absolute values of the numbers. The absolute value of 7 is 7, and the absolute value of -7 is also 7. Since the numbers have opposite signs, we subtract the absolute values. Subtract: 7 - 7Perform Subtraction: Perform the subtraction of the absolute values. Calculate: 7 - 7 7 - 7 = 0Decide Final Sign: Decide whether the final answer will be positive or negative. Since we are adding a positive number to its negative counterpart, the result will be zero, which is neither positive nor negative.

Identify Signs: Identify the signs of the two numbers to determine if they are negative or positive. $\newline$ We have $7$ which is positive, and $-7$ which is negative. $\newline$ Since one number is positive and the other is negative, we will be effectively subtracting their absolute values.
Determine Operation: Determine whether to add or subtract the absolute values of the numbers. $\newline$ The absolute value of $7$ is $7$ , and the absolute value of $-7$ is also $7$ . $\newline$ Since the numbers have opposite signs, we subtract the absolute values. $\newline$ Subtract: $7 - 7$
Perform Subtraction: Perform the subtraction of the absolute values. $\newline$ Calculate: $7 - 7$ $\newline$ $7 - 7 = 0$
Decide Final Sign: Decide whether the final answer will be positive or negative. $\newline$ Since we are adding a positive number to its negative counterpart, the result will be $0$ , which is neither positive nor negative.
