    If you can match those numbers that's good. Different revision numbers may work but always try to get the exact same one.

One last question. Have you used the technique in the video more than once? In the video which numbers of yours matched?

    Not too interesting actually, it would just flip the one in the 1 quadrilionth place, but since it doesn't display numbers that big it would overflow with a garbage output of mostly 9s.

    question. so for division operation can be done in 1000s and get answer fast. but lets say we are multiplying, only possible to rotate clockwise and counter only up by 1. example, 342x130, you have to turn 130 times to get answer. right?

    No. The turn counter shifts as well so you can use the same method. 100x1 first, then 10x3
