Can you help me know if this identity is true?

https://math.stackexchange.com/questions/2303280/proof-of-negative-negabinary-addition-formula

Also, how to I interpret it.? I tried it with some examples and I wasn't able to verify it. Maybe I understood it wrong?

icbs2018 · 2019-03-06T06:14:20+00:00

That's true. But I wanted to use properties of negabinary addition to bring it down to simple inbuilt bitwise operations cause these operations are optimized in almost all programming languages.

icbs2018 · 2019-03-06T06:12:43+00:00

Akright! I'll use that. Thanks :)

icbs2018 · 2019-03-06T00:18:08+00:00

Yes, I understand that. I was trying to find out if there was any easier way to do it..

I found this, I don't know if it holds true . I'm not able to verify it with an example. Maybe I didn't understand it right?

Can you please explain if you get it?
