We tried lots of different calculations and we think that we have come up with all of the answers:
4+4-4-4=0
4+4-4/4=1
(4/4)+(4/4)=2
4x4-4/4=3
4-4x4+4=4
4x4+4/4=5
4+4/4+4=6
4+4-4/4=7
4x4-4-4=8
(4/4)+4+4=9
(4+4+4)-(square root 4)=10
(4x square root 4)+4+4=12
(4x4)-(4/4)=15
(4x4)+(4/40)=17
Theese are what we worked out, we hope that they are correct!
