There are some square roots that you should know off the top of your head, and those are the square root of the "perfect square numbers:" 1, 4, 9, 25, 36, 49, 64, etc. We work with these often. If there is a negative under the square root sign, we call that an imaginary number, but if there is a negative outside the root, like -root 36, we can think of that as the opposite of the root of 36, which would be -6. We can multiply integers by roots as well, and simplify.
