    to help you understand, look at it this way,

    01100111 +
    00011011 =
    01111111

    it can only ever be on, off; true false, or positive negative...

    hope this helps mr dumb

    Are we talking about binary addition?
    Then 1+1=10 (binary) as true as 1+1=2 (decimal).
    We are not talking about boolean algebra here, where 1+1 indeed =1, but pure binary arithemtics.

    I thought Boolean algebra was what you used on a search engine. You know, Thousand AND Young OR FabianFnas kind of thing...

    That's true.

    Boolean algebra is used in googling, database filtering, programming conditional if-statements, constructing digital electronics, logic reasoning - and solving exam problems in boolean algebra.

    In pure boolean algebra we use addition (+) and multiplication (*) and negation. In database filtering, and programming, we use OR, AND and NOT. In electronics also NOR, NAND and XOR are used.

    The one who invented this algebra was George Boole (1914-64), publishing his new thoughts 1847, now implemented in elecronics and computer science. He was well before his time.

    However, binary aritmetics was well before Boole. It is used by a Inca, using knots on a rope. (Perhaps I'm wrong.)

    i was under the impression is was binary to decimal.. so you're right there, there is no 4 or 256 in binary... however you're still wrong...

    in binary, it would be 10+10=10... you are wrong to say 100, its not, 1 + 1 = 1 or 0 + 1 = 1, 0 + 0 = 0.... there is no additional digit.... mr dumb!
    Before calling anyone 'mr dumb' it would be wise to get your facts straight. Confusing Boolean Algebra with binary makes you the 'mr dumb'.

    10 + 10 = 100 !

    10 + 10 + 10 + 10 = 1000

    OK?

    Nice. I had never noticed that, but it makes perfect sense.

    the question was, in binary what is 10 + 10 and you said 100... what you have done here is convert the answer to decimal (4) then convert it back to binary (00000100)... that is wrong, decimal has nothing to do with it, in binary 10 + 10 = 10... that is because 1 + 1 = 1 in binary like i keep on telling you mr dumb

    anyone who's a musician should get that
    gave it away a bit XD
    Octave (8) + Octave (8) = Compound octave (15)

    they simple tells me there's a link there... so what... you try explaining it... considering i write assembly language using numeric machine codes and other constants needed to program a particular cpu architecture i would hope i know how binary works little man

    Well, we're talking about the binary numeral system here which, evidently, you know nothing about.

    yes, binary numeral which used 0's and 1's - not 4's... um.. that would be decimal, so why do you insist on converting binary in the same manner
