Identify Signs: Identify the signs of the numbers involved in the subtraction. We have -1 (which is negative) and -9 (which is also negative).Add Absolute Values: Since both numbers are negative, we will be adding their absolute values. The absolute value of -1 is 1, and the absolute value of -9 is 9. Add 1 and 9.Perform Addition: Perform the addition of the absolute values. 1 + 9 = 10Determine Sign: Determine the sign of the final answer. Since we are subtracting a larger negative number (-9) from a smaller negative number (-1), the result will be negative.Combine Result: Combine the result from Step 3 with the sign from Step 4 to get the final answer. -1 - 9 = -10

Identify Signs: Identify the signs of the numbers involved in the subtraction. $\newline$ We have $-1$ (which is negative) and $-9$ (which is also negative).
Add Absolute Values: Since both numbers are negative, we will be adding their absolute values. $\newline$ The absolute value of $-1$ is $1$ , and the absolute value of $-9$ is $9$ . $\newline$ Add $1$ and $9$ .
Perform Addition: Perform the addition of the absolute values. $1 + 9 = 10$
Determine Sign: Determine the sign of the final answer. $\newline$ Since we are subtracting a larger negative number ( $-9$ ) from a smaller negative number ( $-1$ ), the result will be negative.
Combine Result: Combine the result from Step $3$ with the sign from Step $4$ to get the final answer. $\newline$ $-1 - 9 = -10$
