GenelleBabee: it becomes a positive because when you multiply two negatives it becomes a positive, & it's the same thing with division.

you can divide two negative numbers easily! think,if a bad thing (which represents a negative number) happens to a bad person (which also represents a negative number) is a good thing/positive, which means positive number! EXAMPLE: -20 divided by -4=40! (bad thing/negative) divided by (bad person/negative)= good thing/positive
When you divide or multiply positive and negative numbers, you first do the division or multiplication as normal. The next step is to assess whether or not the answer will be negative or positive. If the two numbers of the question were the same (negative and negative or positive and positive) then the answer will be positive. If the two numbers in the question were different (one negative and one positive) then the answer will be negative. Thus, if you divide a negative number by a positive number, the result will be the same as normal division, but the answer will be negative.
you add them together and divide them by 2
You add the two numbers and then divide it by two. It basically doing the mean which is adding all the numbers and dividing it by how many numbers there are. I hope this helped!
When you multiply or divide two numbers . . . -- If they both have the same sign, then the result is positive. -- If their signs are different, then the result is negative.
