Answer 2

Actually, that is not correct. The sum of multiple negative fives should be calculated by multiplying the number of negative fives by -5.

For example, if you have 4 negative fives, the sum would be:

(-5) + (-5) + (-5) + (-5) = -20

So, the sum of multiple occurrences of -5 is indeed -20, but it depends on how many times you add -5. If you have a different number of -5s, the sum will change accordingly.
