That all depends on the functions you are given for the problem! When you add or subtract from the original function, then we obtain the new function.
If you combine the functions with different domains, then the domain of the addition/subtract obeys whatever domain other function has. For instance:
f(x) = 1/x and g(x) = x
f(x) + g(x) = (1/x) + x
= (1 + x²)/x
Then, the domain is all real values except 0 since x = 0 makes the denominator zero, hence making the whole expression undefined. If x = 0, then this makes f(0) undefined.

Would you add or subtract to negative numbers?
Whatever is required by the context of the question. Whether or not the number is negative gives no indication as to whether to add or subtract.
What do you do when subtracting a positive and a negative?
If you subtract a negative from a positive, add both of their absolute values. If you subtract a positive from a negative, add both of their absolute values and multiply by negative one.
What is your positive and negative?
positive is to add and negative is to subtract in math
What is the inverse operation of add negative 6?
subtract negative 6 or +6
Simplify the following expression 33z-4-20 z-5?
I am assuming that the original equation is 33z-4-20=z-5. Subtract z from both sides. Add 4 to both sides, as well as add 20 to both sides. Divide both sides by 32.
