(f+g)(x) is shorthand notation for f(x)+g(x). So (f+g)(x) means that you add the functions f and g


(f-g)(x) simply means f(x)-g(x). So in this case, you subtract the functions.


(f*g)(x)=f(x)*g(x). So this time you are multiplying the functions


and finally, (f/g)(x)=f(x)/g(x). Now you are dividing the functions.
