Find the product. (-3)(5)(-5)(-4) A) -300 B) -200 C) 200 D) 300

dangina [55]

The answer is A) -300

The easiest way to solve this is to just multiply all the numbers and ignore the signs. From that, you would get : 300. Now, count how many negative signs there are. If there is an even amount of negative signs, the answer will be positive; likewise, if there is an odd amount of negative signs, the answer will be negative.
