How do I get the numbers one through 20 only using six '1's

The integers from 1 to 20 can be represented by using six ones and the mathematical operations such as addition subtraction multiplication and division allowing for the use of parentheses exponents and decimals. Do not forget to follow the correct order of operations. Try to represent the Integers from 1 to 20 by using six '1's in the above conditions. 
Example 7 = (1+1) • (1+1+1) +1

14=(1/.1)+1+1+1+1
15=11+1+1+1+1
16=(1+1+1+1)^(1+1)
17=(1+1)/(.1)-1-1-1
18=(1+1)/(.1)-1-(1/1)
19=(1+1)/(.1)-1+(1-1)
20=(1+1)/(.1)+1-(1/1)
