In multiplication, a negative times a positive has a negative answer. if both are positive or both are negative, the answer is positive. 
5 * -5 = -25
-5* -5 = 25
in divisions say you have
 -5/5 = -1
-5/-5= 1
5/-5= -1
in addition and subtraction, subtracting a negative means to add the two numbers. adding a negative means to subtract the second number.
5+ (-5) = 0
5- (-5) = 10

Answer:
7. 
8. 
Step-by-step explanation:
We are given two function, f(x) and g(x).
We want to find their addition and their subtraction, and we do this combining like terms.
The functions are:


 7. Find (f+9) (x) 

So

 8. Find (f - g) (x)

So
