Rewrite as Addition: Subtracting a negative number is the same as adding its positive counterpart. Let's rewrite the subtraction of a negative number as the addition of a positive number. -7 - (-4) becomes -7 + 4.Determine Sign: Now we need to determine if the final answer will be positive or negative. We compare the absolute values of the numbers we are adding. The absolute value of -7 is 7, and the absolute value of 4 is 4. Since 7 is greater than 4, the answer will be negative.Perform Addition: We add the numbers, keeping in mind that the result will be negative because the larger absolute value is from a negative number. 7 - 4 = 3 Since we determined the answer will be negative, the result is -3.Final Result: We have completed the calculation without any mathematical errors, and we have found the result of the subtraction. -7 - (-4) = -3

Rewrite as Addition: Subtracting a negative number is the same as adding its positive counterpart. Let's rewrite the subtraction of a negative number as the addition of a positive number. $-7 - (-4)$ becomes $-7 + 4$ .
Determine Sign: Now we need to determine if the final answer will be positive or negative. We compare the absolute values of the numbers we are adding. $\newline$ The absolute value of $-7$ is $7$ , and the absolute value of $4$ is $4$ . Since $7$ is greater than $4$ , the answer will be negative.
Perform Addition: We add the numbers, keeping in mind that the result will be negative because the larger absolute value is from a negative number. $\newline$ $7 - 4 = 3$ $\newline$ Since we determined the answer will be negative, the result is $-3$ .
Final Result: We have completed the calculation without any mathematical errors, and we have found the result of the subtraction. $\newline$ $-7 - (-4) = -3$
