Overlapping CalcuDoku (Square Wisdom, MathDoku) puzzle

It’s been quite a while since I last posted a CalcuDoku puzzle. I’m going to fix that now and to make it up to you, it will be a somewhat special variant of Square Wisdom puzzles. It’s an overlapping, 2 in 1 (Gattai-2), CalcuDoku puzzle, which is essentially in a TwoDoku layout. Remember the rules: there are no 3×3 nonets (nor any other kind of nonets). You only need to make sure that each row and each column contain one occurrence of each digit. And finally, unlike Killer Sudoku puzzles, in CalcuDoku puzzles numbers can be repeated in each cage! Of course, if you need assistance with cage combinations, you can use the CalcuDoku calculator.
