Solutions to Fill the boxes.

I use all numbers one time.

1+3+5+7+9+11+13+15 = 64

64-30 = 34. 34/2 = 17

a+b+c=17 . a = 3, b = 5, c = 9 The boxes are A, B and C.

One solution is A [15+1 -3] +B [13+7 -5] +C [11 - 9] = 30

There are a lot of solutions!

Another solution is : a=1, b= 3, c = 13 A [5+7 - 1] + B [9 - 3] +C [15+11 - 13] = 30
