Four 4s Challenge - Make 1-20 with only four 4s

This is one of my favorite math puzzles ever! See if you can come up with numbers 1-20 using only arithmetic symbols and four 4s. Try it on your own, but stay tuned for Huzefa's explanation. Check back every Friday for more awesome math puzzles!

Is there any way to do 11, 13, and 18 without using square roots? Because I know it is possible to solve other numbers without using square roots, but I can't seem to do 11, 13, and 18.
