1. Is it a Korean kid?
2. ok for those of us who have no idea about this stuff is this like... impressive or not idk am i meant to marvel idk what my reaction is
3. the rearing of children like this is great but slightly unfair to those unfortunate children who don't have educated parents. the world is unfair I guess
4. Big deal, my computer does this all the time.
5. pshhh i can do this with my eyes closed while jumping on the trampoline with hay fever pollen count high
6. Binary addition isn't that hard..?

That's what I think as well.

It's basic maths just using 0s and 1s. Im sure loads more 8 year olds can do this!

Binary addition isn't really any more difficult than decimal addition. The only reason it seems difficult is because we spend our childhood learning to count in decimal and are very used to it.

What the kid does here is not difficult if you've practised binary addition a little bit, but still fairly impressive for someone his age to have gone to the effort of doing so.

Binary multiplication on the other hand is something I would struggle to do as I've never practised it at all.

Multiplication really isn't much harder than addition, you don't even have to memorise any tables, since you can shift left.
12. For those who don't do computing, it's not a complex concept
0 + 0 = 0
0 + 1 = 1
1 + 1 = 0 carry 1
1 + 1 + 1 = 1 carry 1

You forgot:

1 + 1 + 1 + 1 + 1 + 1

Without converting to decimal and back again it's a little less obvious on how one would calculate that using binary arithmetic alone
14. I would have been able to do that too when i was 8 years old tbh! Binary addition is not hard...
