## Function Operations Calculator

If we imagine the first function as the detergent and the second function as the softener, evaluating a function operation is like doing laundry.

When we evaluate a function operation, we can plug the input into each function separately and then combine their outputs using the given operation ($+,−,×,÷$).

This is like applying detergent and softener separately on dirty clothes to get clean, soft clothes.

Alternatively, we can combine the two functions using the given operation ($+,−,×,÷$), and then plug the input into the combined function to determine the final output.

This is like using a pod that contains both detergent and softener to turn the dirty clothes into the clean, soft clothes.

Notice that both methods get us the same final results!
