Four Fours

The challenge is to construct all the numbers between 1 and 20 using **exactly** four 4s and any of the four basic math operations (addition, subtraction, multiplication, division)

**Caution**: remember "order of operations" (BEDMAS)

Here's the first two to get you started ...

**1** = (4 + 4) / (4 + 4)

**2** = (4 x 4) / (4 + 4)
