11 = 1*8 + 1*2 + 1*1 = 1(2)3 + 1(2)1+ 1(2)0.
Thus, in binary (base 2) 11 is represented as:
1011.
To double check we get:
8 + 2 + 1 = 11 (base 10).

14 decimal in binary is 11102. In octal it is 168 and in hexadecimal it is 0E16.
1111 converted from binary (base 2) to decimal (base 10) is 15 When you expand the steps... 1111 binary = (1 X 2^3) + (1 X 2^2) + (1 X 2^1) + (1 X 2^0) = 8 + 4 + 2 + 1 = 15
The binary number 10011 is equivalent to the decimal number 19 in the base-10 number system. In binary, each digit represents a power of 2, starting from the right with 2^0, 2^1, 2^2, and so on. Therefore, 12^4 + 02^3 + 02^2 + 12^1 + 1*2^0 = 16 + 0 + 0 + 2 + 1 = 19.
Both base 16 and base 2 number systems use binary numbers (1 and 0) to write out and define decimal numbers.
