what do you mean by A? if 18 divided by -6 the answer is -3.

A. Because 3*6 = 18, and you have the factor -6, the remaining factor must be -3.

B. I assume it wants you to show your work for long division.

Note: it would help if you were more clear in posing the question.

As mentioned above, it is not clear what is to be demonstrated. I will present another attempt.

Factorize 18 into prime factors. Since division by negative numbers is possible, include two factors of -1. So

18 = (-1).(-1).2.3.3

Now organize the prime factors into two groups A (in bold) and B (italized).

18 = **(-1).2.3**.*(-1).3*

Therefore 18/(-6) equals

group B=(-1).3= -3
