Identify Signs: Identify the signs of the numbers involved in the subtraction.We have −5 and −(−4). The first number is negative, and the second number is also negative, but we are subtracting a negative, which is the same as adding a positive.
Convert to Addition: Convert the subtraction of a negative number into the addition of a positive number.Subtracting a negative is the same as adding its positive counterpart. So, −5−(−4) becomes −5+4.
Add Numbers with Signs: Add the two numbers, keeping in mind their signs.We are adding −5 and +4. Since they have different signs, we subtract the smaller absolute value from the larger absolute value.Calculate: 5−4
Perform Subtraction: Perform the subtraction.Subtract the absolute values: 5−4=1
Determine Final Sign: Determine the sign of the final answer.Since the absolute value of the original negative number −5 is larger than the absolute value of the positive number 4, the result will be negative.
Combine Result: Combine the result of the subtraction with the determined sign.The result of −5−(−4) is −1.
