How do I get numbers 1-20 using six twos?

Question

Question is above.  How to use 6 2's to get 1-20

Answer 1

Assuming we can use the 2 in ²√ and as an exponent, I can get you started.

 

1 = (2 + 2 + 2)/(2 + 2 + 2)

 

2 = (2 + 2 + 2 + 2)/2 - 2

 

3 = ²√[2(2)(2) + 2/2]

 

4 = [2(2)(2)(2)] / [2(2)]

 

5 = [2(2² + 2/2)] / 2

 

Can you keep it going from here?
