Sean says that to add a number to -100 and still have -100 is to add zero. candice says that she can add two numbers to -100 and still have -100 who is correts and why

Both are right b/c like sean says you can add zero and itll still be -100 but candice is also right b/c because you can add any # to that -100 but you can also add a negative # to get it back to -100. for example: -100+23= -77 but if you also add a negative 23 it would be right back to -100.
