As the title says, the goal for this puzzle is making 1353 out of simply 4, 4, 4 and 4. Concatenation is not allowed. Here are all of the allowed operators.

  1. Addition (+), Subtraction and negatives (-), Multiplication (*), Division (/)
  2. Roots (√), Exponents (^)
  3. Decimals and repeating decimals (.)
  4. Percentages (%), which divide a number by 100

Hint: It has something to do with two thirds.

You may use up to 20 operators. Good luck!
