Question

The binary addition 1+1+1 gives?
​

Answer 1

Answer:

Something similar happens in binary addition when you add 1 and 1; the result is two (as always), but since two is written as 10 in binary, we get, after summing 1 + 1 in binary, a digit 0 and a carry of 1.

Answer 2

The binary addition 1+1+1 gives 11.

Binary addition is similar to regular addition (decimal addition), with the exception that it uses a value of 2 instead of a value of 10. For example, adding 8 + 2 in decimal addition yields ten, which you write as 10; in the sum, this yields a digit 0 and a carry of 1.
