Recognition is dependent on the base system!  Odd base systems require that the quantity of places that have odd values is even.  Even only requires that the 'ones' place value is even.  Fifty percent of all integers and non-repeating decimals are even, therefore, divisible by two.  Dash Block representations enable a quick and simple process for dividing by two.

The binary number system that computers use is inherently structured around multiplication and division by two as the place values are powers of two’s.  In the decimal number system multiplication and division by two can easily be extended to include five just by shifting the decimal point.
