Identify Signs: Identify the signs of the numbers involved in the subtraction.We have −4 and −(−2). The first number is negative, and the second number is also negative, but since it is being subtracted, it becomes positive (subtracting a negative is the same as adding a positive).
Rewrite Subtraction: Rewrite the subtraction of a negative number as the addition of a positive number.So, −4−(−2) becomes −4+2.
Add Numbers with Signs: Add the two numbers, keeping in mind their signs.Since we are adding a negative number (−4) and a positive number (2), we find the difference between their absolute values.Subtract the smaller absolute value from the larger one: 4−2.
Perform Subtraction: Perform the subtraction.Calculate 4−2 to get 2.
Determine Final Sign: Determine the sign of the final answer.Since the original number with the larger absolute value was negative (−4), the result will also be negative.So, −4−(−2)=−2.
