Note : A # B = A*10 + B
Arrange the numbers 1 to 9 to green triangles, and arrange operator (+,-,x,/,^, and #) to the white triangles, so the math operations below are equals.
(((A op1 B) op2 D) op4 F) = constant
(((F op4 G) op5 H) op6 I) = constant
(((I op6 E) op3 C) op1 A) = constant
A x F x I = constant
