Ответ:
always going to be negative.
explanation: i'm pretty sure the question is asking the rule that will always be true for multiplying three negative numbers, so that's what i'm answering based off of. no matter what, if you multiply three negative numbers, the answer is going to be negative. if you multiply two negative numbers, it will equal a positive number. if you multiply a positive and negative number, it will equal a negative number. so, multiplying three negative numbers is like multiplying a positive and negative number, and your answer will always be positive.
hope this helps and have a great day. if there are any mistakes in my answer please let me know so i can fix them :)
