Can you solve the rest?

Today in maths we were problem solving in teams. We were trying to find every number from 1 to 20 using only four 4s.  This meant that we had to use the number 4 four times, but we could use any operation.

Once a group had a solution they would write it only board next to the number the equation came to.

We also needed to remember the order of operations (BEDMAS)
1. Brackets
2. Exponents
3/4. Division/Multiplication
5/6. Addition/Subtraction

Here are the solutions so far.  Check to see that they are correct and if you solve any more, add the solutions in as a comment.
