1.Normal Sudoku rules apply.
2.The digits outside the grid:

Black digits indicate the amount of Arithmetic Groups in that row or column.
Red digits indicate how many cells are occupied by the Arithmetic Groups in that row or column.
Green digits are in the Arithmetics Groups shown in reading order(left to right,top to bottom) of that row or column.
Arithmetic Group: If three consecutive cells A,B and C in the same row/column fulfills A ※ B = C (※ refers to one of the operators aka. addition, subtraction, multiplication and division), then A B C form a Arithmetic Group. The locations of A B C cannot be switched.(which means, 5 3 8 is a Arithmetic Group while 5 8 3 isn't)
