10011.
That IS the binary code.
'2' Decimal code => '10' Binary code.
18 in binary is 10010
3 converted into binary code is 00000011
10011
(10011)2 = (19)10
10011.
19
19 in binary is... 10011 (16+2+1)
it is itself in a binary form :) but if its in decimal form.. then its binary equivalent will be..(10011100011011) if it is in binry form.. its equivalent will be..(19)
the sum of (1001+1010)is=(10011)
10011 binary or 19 in decimal.
10011
That IS the binary code.
If 10001 = 19, it is in an irregular non-integral base. (In binary, 10001 = 17, 10011=19, and 10100 = 20.)
