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.

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.)

no its not, you're 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!
10 + 10 = 100 !
10 + 10 + 10 + 10 = 1000
OK?
