ON EDGE: Yellow & Lavender (part A)

Normal 6x6 sudoku rules apply.

Each spot along a coloured edgeline has a value, found by performing a calculation using the two digits it sits between:

• Sum (+) spots: The value of a spot with a plus sign equals the sum of the two digits it sits between.
• Difference (-) spots: The value of a spot with a minus sign equals the larger digit minus the smaller digit.
• Product (x) spots: The value of a spot with a multiplication sign equals the product of the two digits.
• Ratio ( / ) spots: The value of a spot with a forward slash equals the larger digit divided by the smaller digit. (The value will always be an exact integer.)

• Yellow lines are 'edge nabners'. No two spot values anywhere on the same edge nabner may be equal or consecutive.
