Adding, or Multiplying The Fun

Normal Sudoku rules apply. Numbers in circles and pills are to be used in the calculations with addition (+) or multiplication (x) on one side and the result on the other side of the (=) sign. If circles and pills are next to each other, with no symbol between, they are part of different calculations than one another. Cells with a black dot between them are in a ratio of 2:1. Not all possible dots are shown.
