Find a 3x3 Magic Square where each row, column and both diagonals result in positive number 9
You are allowed any of the 4 math operations : add, subtract, multiply or divide. NO OTHER OPERATIONS ALLOWED
You must use numbers 1 thru 9 (positive integers only, no negative signs within the number boxes). All 9 numbers must be used.
You can use a Square root or Cube root or a Factorial function WITHIN the number box only. No other function allowed. For example the number box can say 3! which would be a value of 6 but you have used the number 3 only.( you cannot use 3 somewhere else). If you use 3! then you must use 6 somewhere else. The square must show all 9 positive integers.
Mathematical operations must be in the direction of the arrows. No programming.
I found one solution but there may be more.
As a broader question can one program the square to get any number (not just 9) with multiple math operations using 1 to 9??
