Aliquantulus is right. People who don't understand what this is are flipping burgers and dealing with irate customers. I understand this, I also understand software engineering, and I'm making damn good money too

theres a thing called a computer that can do that for you. what year are you living in? 1607? 1558? 5 B.C.?

This is most likely a model to show people how a computer works. A computer only works in binary, and addition and multiplication are carried out in this manor within the computer in an electronic circuit.

Hmmm.
He say's it's an adding machine, but in the end, he has to add numbers together to get to the final answer.
It's an accumulator, not an adding machine. He calls it a "result state" which...
Sure, if you happen to know that all the "bits" to the right of the last bit, are the next bit - 1, then it's easy to know that 11111 = 31. But if you had to add 16 + 8 + 4 + 2 + 1 = (unclear by inspection)
= waste of time.

Guys, this is really not waste of time.
This is actually how computer works with numbers (yes, in exactly this binary format).
And for jayjay101:
Yes, this model is even for subtraction:

Just use brain and you will understand that.

I could simply use something called. A BRAIN... What are you? Kids? Who the fuck would need this. Plus, Kids got parents and teacher to teach them. Parents would be best(Home schooling)cause pubic school is not worth it. Don't ask why. Take your kid to public school and he will have sex with like 7 girls and will die by drugs. Freaking useless public school.
Anyways, This is pretty useless invention. Everything has a use... but, This is PRETTY f-ing useless. Stupid, retarded, junk, waste of wood, Waste and time to make, etc.
-goes ALL the way to where he lives and punches him and goes allll the way back home-

i'm guessing you never had sex noureddin... how sad...
BTW not everything has a use.. most things don't have a use and of course one of the things without use is people like you who complain about everything and do nothing... just waiting for someone else to screw up...
I pity you for your arrogance... your insecurity... your low self esteem... and your small c**k...

@Noureddin, you must have had a sad, sad life. May it be short.
Anyhoo, this machine might not work for numbers beyong 64, but the very conceptualisation is pretty intelligent. Two Thumbs up, I dig clever devices. Even if they are limited.
