There are 3 Rules:
 
Rule 1: A positive number divided by a positive number gives you a positive number.

Example 1: This is the kind of division you’ve been doing for years, positive numbers divided by positive numbers. It would look like this: 12/3 = 4. 12 is positive, 3 is positive, thus, 4 is positive. We know that 12 and 3 are both positive because there are no negative signs in front of them.

Rule 2: A positive number divided by a negative number gives you a negative number.

Example 2: This is new – for example, you might have 12/-3. The 12 is positive, but the 3 is negative, so our answer has to be negative. Thus, we divide the numbers as we normally would, and then put a negative sign in front of our answer. So, 12/-3 = -4. Please note that this also works when the negative number comes first and the positive number is second. For example, you may see it written -12/3 = -4, but don’t get confused. The combination of one positive and one negative number, no matter which order they come in, means your answer is going to be negative.

Rule 3: A negative number divided by a negative number gives you a positive number.

Example 3: This is also new—and doesn’t seem to make much sense, but it is a rule we have to follow when dividing negative numbers. So, for example, we may have the problem -12/-4. Both the 12 and the 4 are negative, so we know our answer is going to be positive. Therefore, -12/-4 = 3.

Negative times a Negative equals a Positive
Negative times a Positive equals a Negative
Positive times a Positive equals a Positive.
Positive times a Negative equals a Negative.
 
So a Negative divided by a Positive equals a Negative
Because,
A Negative times a Negative equals a Positive.
 
A/-B = -C because -C * -B = A
-A/B = -C because -C * B= -A
A/B =  C because C * B = A
-A/-B = C because C * -B = -A
A positive divided by a negative equals a negative.  A negative divided by a positive equals a negative.  It takes to negatives to make a positive when multiplying or dividing.
