Today’s puzzle is a diagonal Kendoku variant. In addition to all other standard Kendoku rules, there is one extra for this puzzle: the numbers cannot be repeated on either diagonal, just like they can’t be repeated on any row/column. This is marked in the puzzle with an “X” across.
I’m posting two versions of the same puzzle: one with all operators filled in and one with very few operators. Choose the one you prefer. The one with reduced number of operators is obviously more difficult, but solvable!

interesting puzzle. It’s the variations that make this site so great.
