Identify Operation: Identify the operation to perform first.We have a subtraction followed by subtracting a negative number, which is equivalent to addition. So, we will first deal with the subtraction of a negative number.Calculation: −2−(−4)=−2+4
Perform Addition: Perform the addition from Step 1.We add the opposite of −2, which is 2, to 4.Calculation: −2+4=2
Subtract Last Term: Subtract the last term from the result of Step 2.Now we subtract 2 from the result obtained in Step 2.Calculation: 2−2=0
