Yes it is, let me explain it in simple way to learn it forever as I learnt it in same way
a -ve number is enemy
a +ve number is friend
so
-ve (enemy) x +ve (enemy's friend) is all your enemy (-ve)
-ve (enemy) x -ve (enemy's enemy) is always your friend i.e. +ve
+ve (friend) x +ve (friend's friend) is always your friend i.e. +ve
+ve (friend) x -ve (friend's enemy) is always your enemy i.e. -ve
I am sure above trick will help you learn it forever :)
keep it up

A negative and a negative person find each other. Is this a good or bad thing?
Good. Positive. They will get along. Here's how you could write this in math-form:
-8 x -2 = 16
(Negative eight times [or multiplied] by negative two equals sixteen)
