Final answer:
To find the expression that has the same value as 18 - (-3), we need to simplify the subtraction. Therefore, 18 - (-3) is equivalent to 18 + 3, which gives us 21. None of the given expressions have the same value as 18 - (-3), so the answer is None of the above.
Step-by-step explanation:
To find the expression that has the same value as 18 - (-3), we need to simplify the subtraction. When subtracting negative numbers, we can change the sign to addition and then combine the terms.
Therefore, 18 - (-3) is equivalent to 18 + 3, which gives us 21.
None of the given expressions have the same value as 18 - (-3), so the answer is None of the above.
