Initial Setter Difficulty: 2.5 / 5

Normal Sudoku rules apply
Place the digits 1-9 so that they do not repeat in any row, column, or 3x3 box.

Coordinate Arrows
The two digits on an arrow give the coordinates of a particular target cell somewhere in the grid. The digit on the arrow's shaft indicates the target cell's row, and the digit on the arrowhead indicates the target cell's column. The sum of the two digits should be placed into the target cell. No two arrows target the same cell.

Hint to start

There are 21 arrows, it's worth considering how many digits/cells can be referenced.
