note: this is the fixed version of a puzzle I had posted earlier in which I had transposed two clues.

Rules

• Standard sudoku and killer sudoku rules apply
• Every row, column and 3x3 box must contain the digits 1-9
• Digits may not be repeated inside cages
• The letters A,E,G,K,N,O,R,S, and T each correspond to a different digit 1-9
• The cells with a letter in a black circle contain the digit that corresponds to that letter
• In the upper left corner of most cages are two letters that represent the sum of the digits in that cage
• In some cages the two letters represent a 2 digit number where the first letter is the tens digit and the second is the units digit.
• In other cages the two letters should be multiplied together to give you the sum
• Example: If X was 2 and Y was 7, then a cage with XY in the corner could have a sum of either 27 or 14 (2 x 7).
