Question 119413
ok when adding and subtracting negative numbers 
is very simple.
when adding and subtracting
the bigger number is gonna carry the sign
if the bigger number is negative
its gonna be negative
if the bigger number is positive 
its gonna be positive

ex: -12+4=
since -12 is bigger the answer is gonna be negative
-12+4= -8

ex: 12-4=
since 12 is bigger number the answer will be positive.
12-4=8

*Now the way I remember about multiplying and dividing
negative and positive numbers is really cool.

Its called the love boat!
*now if two people are in a reltionship are 
always positive then their re;ationship will be positive

*now if two people are in a relationship and they are 
always negative, they agree on everything then their 
relationship will be positive.

*now if two people are in a relatioship, one is always 
negative and the other is positive, they will never 
agree so the relationship will be negative

I hope you understand this.
here are a few examples.

2*2= 4 (two positives equal a positive number)
-2*2=-4 (one negative one positive equals a negative number)
-2*-2=4 (two negative numbers equals a positive number)
good luck!
