1.Aroundoku uses 6 of the digits 0-9 to be determined by the solver. Place one copy of each digit determined in each Row/Column/Box.
2.The number on the black cells is the result of the non-black cells that`s orthogonally adjacent to it using one of the mathematical operations(addition, subtraction, multiplication, division).The mathematical operation used is to be determined by the solver.
*With subtraction sums, you must subtract the smaller numbers from the largest number. With division sums, you must divide the largest number by the smaller numbers. Numbers may repeat around a black cell, as long as it is allowed by other rules.
Here`s the puzzle,it might be a little tricky to solve:
Finally,here is an example in 6x6(4 digits to be determined)
Solution code: Row 2 followed by Column 5 (12 digits, no spaces, skip black cells.)

Removed some misleading sentences from rules.
Replaced the example with a new one.

Thanks for explaining. To help you out, I asked the first question because the example grid had zeros, so it was unclear which digits were being added. I asked the second question because of the first asterisk* sentence in the rule set. I thought you were saying that different operands were allowed. Now I don't understand that sentence :)
--Reply: Thanks for the feedback. Originally, that sentence was intended to say that its possible a hinted 3 can have different operands leading to it (6-2-1 or 6/2/1),but after giving it a thought it does feel like redundant. I removed that sentence and replaced the example with a new one basing on your feedback.

Rules clarification please. (1) Does the clue have to include ALL orthogonally adjacent digits? (2) Can there be multiple operands in a calculation?
Example: for the 13 clue in box 2, could the digits be 3,4,5,6... (3x4)+6-5=13?
---Reply:(1)Yes.(2) No. You can only use one of the operands for each clue. That means the 13 can only be sum of its surrounding numbers.
