Could someone explain to me why is it important to simplify radical expressions before adding or subtracting?

It is not really important, but you can say that it makes computation easier.

Consider this example Add: \[\sqrt{s} \sqrt{?}\] \[\sqrt{s} \sqrt{?}\] Start with the given expression. Can you add these two radicals in this state? The answer is simply no. We need to simplify the radicals. Take the square root of 4 to get 2. Take the square root of 16 to get 4. In this step we have simplified the radicals. Add 2+4 So simplifies to 6. In other words,
