**3/5**A binary number is made of 0s and 1s. In the binary number system only two symbols, 0 and 1, are used to represent numeric values. The symbol “0“ represents the value “zero” while the symbol “1” represents the value “one”. Since there are only two symbols in the binary number system, the value “two” is represented by placing the symbol “1” on the left–hand side of the symbol “0” resulting in the binary equivalent “10”. Next, the value “three” is represented by “11” in the binary number systemby replacing the “ 0 ” in “10” by the next higher value symbol “1”.
