Answer:
-45.
Explanation:
To find the value of the expression -23 + (-20) + (-1) - 1, we can simplify it step by step. Step 1: Add the numbers with the same sign: -23 + (-20) + (-1) - 1 -23 and -20 both have a negative sign, so we can add them together: -23 + (-20) = -43 Step 2: Add the remaining numbers: -43 + (-1) - 1 Now, we have -43 and -1 left. Both of these numbers have a negative sign, so we can add them together: -43 + (-1) = -44 Step 3: Subtract the final number: -44 - 1 Subtracting 1 from -44 gives us: -44 - 1 = -45 So, the value of the expression -23 + (-20) + (-1) - 1 is -45.
