Solve -9.5 + 3 -(-5.5) and show how it is -12

Answer 1

To solve the expression -9.5 + 3 - (-5.5), we follow the order of operations.

First, we simplify the expression inside the parentheses:
-(-5.5) = 5.5

Now our expression becomes:
-9.5 + 3 + 5.5

Next, we add -9.5 and 3:
-9.5 + 3 = -6.5

Finally, we add -6.5 and 5.5:
-6.5 + 5.5 = -1

Therefore, -9.5 + 3 - (-5.5) is equal to -1, not -12.
