What is the outcome when you subtract -9 from 5?

When subtracting -9 from 5, the operation is equivalent to adding 9 to 5. This is because subtracting a negative number reverses the sign of that number. So the calculation would be:

5 - (-9) = 5 + 9 = 14.

Thus, the outcome of the operation is 14, making it the correct answer to the question. Understanding this concept is essential as it illustrates how operations with negative numbers function, which is a key aspect of arithmetic in various mathematical applications.
