Answer 1

To solve the addition problem \(-815 + 415\):

1. Start by rewriting the problem: \[ -815 + 415 \]

2. Rewrite \(-815\) as negative: \[

   • (815 - 415) \]

3. Calculate \(815 - 415\): \[ 815 - 415 = 400 \]

4. Therefore: \[ -815 + 415 = -400 \]

Now, looking at the responses given:

• 415
• Start Fraction 4 over 15 End Fraction
• −1215
• negative Start Fraction 12 over 15 End Fraction
• 45
• Start Fraction 4 over 5 End Fraction
• −415
• negative Start Fraction 4 over 15 End Fraction

None of these options show \(-400\). The closest option in terms of negativity is \(-415\), but that is not the correct answer.

So, the correct answer would be "none of the above." The correct result for \(-815 + 415\) is \(-400\).
