So, to get twelve all you have to do is: 4x(4-(4/4)=12

This simplified would be: 4x(4-1)=12

This simplified would be: 4x3=12

To get 15 you have to: 4x4-(4/4)=15

This simplified would be: 4x4-1=15

To get 16 you have to: 4x4-4+4=16

To get 17 you have to: 4x4+(4/4)=17

This simplified would be: 4x4+1=17
