Madan: The characteristics you just described apply to all numbering systems, regardless of the radix.
In the hexadecimal system, for example, 30 + 10 = 40 too. It's just that 30, 10 and 40 represent different values in the hexadecimal system from those they represent in the decimal (or octal, or duodecimal) system. In any system, 30 represents 3 times the radix, 40 represents 4 times the radix, 100 represents the square of the radix, 2000 represents two times the cube of the radix, and so on.
