Answer :

To solve the expression [tex]\(-65 + 40\)[/tex], we'll break it down into simple steps:

1. Identify the Numbers: The expression involves adding a negative number [tex]\(-65\)[/tex] and a positive number [tex]\(+40\)[/tex].

2. Understand the Operation: Since you are adding a positive number to a negative number, it's similar to subtracting the positive number from the negative number.

3. Perform the Subtraction:
- Start with [tex]\(-65\)[/tex]. To find the result of adding [tex]\(+40\)[/tex] to [tex]\(-65\)[/tex], you're essentially asking: "What is [tex]\(65 - 40\)[/tex]?"
- Calculate: [tex]\(65 - 40 = 25\)[/tex].
- Since the starting number was negative, the final answer will also be negative.

4. Conclusion: The result is [tex]\(-25\)[/tex].

Thus, the answer to the expression [tex]\(-65 + 40\)[/tex] is [tex]\(\boxed{-25}\)[/tex], which matches option C.
