Identify Operation and Signs: Identify the operation and the signs of the numbers involved. We are subtracting -3 by -1. Both numbers are negative.Apply Rule for Subtracting: Apply the rule for subtracting negative numbers. Subtracting a negative number is the same as adding its positive equivalent. So, -3 - (-1) is the same as -3 + 1.Perform Addition of Numbers: Perform the addition of -3 and 1. Add the absolute values and apply the sign of the larger absolute value. The absolute value of -3 is 3, and the absolute value of 1 is 1. Since 3 is greater than 1, the result will have the sign of -3, which is negative. Calculate: -3 + 1 = -2

Identify Operation and Signs: Identify the operation and the signs of the numbers involved. $\newline$ We are subtracting $-3$ by $-1$ . Both numbers are negative.
Apply Rule for Subtracting: Apply the rule for subtracting negative numbers. $\newline$ Subtracting a negative number is the same as adding its positive equivalent. So, $-3 - (-1)$ is the same as $-3 + 1$ .
Perform Addition of Numbers: Perform the addition of $-3$ and $1$ . Add the absolute values and apply the sign of the larger absolute value. The absolute value of $-3$ is $3$ , and the absolute value of $1$ is $1$ . Since $3$ is greater than $1$ , the result will have the sign of $-3$ , which is negative. Calculate: $-3 + 1 = -2$
