Please ONLY answer the question if you 100% know you have it right... will give brainliest+5 stars+thanks for a good explanation

-a•-b=c

-a•b=-c or a•-b=c

-c/-b=a

-c/b=-a or c/-b=-a

Step-by-step explanation:

So with the first one, multiplying or dividing negative numbers pretty much cancels each other out. I don’t remember if there’s any method or tips to add on but yeah

The second one kinda goes hand in hand with the first. You can’t have two negative numbers because the product would be positive and it can’t be both positive numbers because the product would also be positive. Multiplying and dividing by one negative and one positive will result in a negative.

This also goes with the third and fourth one. For the third one, it should be both negative numbers/variables to result in a positive outcome and only one negative if it results in a negative number.

I remember this thing my teacher taught me. Micky Mouse (a positive number) and Chucky (a negative number) would not like hanging out together, resulting in a negative relationship (or a negative number). Mickey and Minnie (positive number) are both happy together do they have a positive (number) relationship. Chucky and Anabelle (Negative number) share common goals and they’re practically the same Ig so they have a positive (number) relationship.

I hope this helped haha. I don’t know whether you’re allowed to reuse numbers so
