Like Father Like Son
Rules:
Normal Sudoku rules apply.
Killer: Digits in a cage cannot repeat and sum to the given total.
Little Killer: Clues outside the grid represent the sum of the digits along the marked diagonal.
Cipher: Clues have been encoded. Each letter stands for a different number from 1-9. A “?” can stand for any number from 0 to 9. Each appearance of “?” is not necessarily the same. The given equations must be true (ie. 2*B means that cage is two times the value of B).
Solution code: Row 8

A challenging cipher, and I like that the puzzle was far from trivial once you have all five letter-number pairs.
I think this might be only the first or second time I've ever spotted a y-wing without bifurcating, so I'm feeling pretty good about that :)

I didn’t even realize there was a y-wing in this puzzle :) glad you enjoyed it!

What a lovely puzzle! First I thought I wouldn't be able to solve it, but after the break in it was a smooth solve. Thank you so much!
