Question

why product (-9)×(-5)×(-6) is negative while (-9)×(-5)×(-6)×(-1) is positive give reason
​

Answer 1

Answer:

There are 3 negatives in the first one, but there are 4 negatives multiplying together in the second equation.

Step-by-step explanation:

When multiplying a negative number by another negative number, then it becomes positive. When a positive in multiplied by a negative, then it bcomes a negative. -9x-5 becomes positive 45. Multiplying the positive 45 by -6 results in -270. If you then multiply the -270 by -1, then it becomes a positive 270.

Answer 2

Step-by-step explanation:

Do you see that (-9)×(-5)×(-6) has three negative numbers? If you add/multiply two negatives together, you get a positive. If you add another negative with it though, the answer would become a negative again.

The same as (-9)×(-5)×(-6)×(-1) instead this one has 4 negative numbers. Once again, if you add/multiply two negative together, you get a positive. Since there is 4 negative numbers, they counteract with each other, therefore making the answer a positive.

Hope this helped!
