Calcudoku 6×6 puzzle

It’s been an age since I’ve posted new puzzles on here directly, mainly because all my puzzle-making effort has been focused on Sudoku Xtra, Sudoku Pro, PuzzleMix and a major book I recently completed.

In any case, there’s no time like the present to fix that so here’s a simple 6×6 Calcudoku. Just place 1 to 6 in each row and column and make sure the given number results when the stated operator is applied between the numbers in each bold region.
