Toroidal Calcudoku puzzle

Another easy Calcudoku in terms of its logic, although this one is a little trickier in practice since it’s 7×7 and is toroidal, meaning that some of the regions wrap around the edges of the grid and continue on the square directly opposite on that row/column.  Other than, just place 1 to 7 in each row and column whilst fulfilling the mathematical results given for each region. Unlike Killer Sudoku, you can repeat a digit within a cage (although of course not a row or column).
