“Do You Know What I Like About Binary Code?”

“Do you know what I like about binary code?”, asked my 4th grader out of nowhere.

“What?”

“Each number has only one way. For example, 20 is 16+4. But if you used 8+4+2+1, that would only be 15, which isn’t enough.”

It is heartwarming to think that he’s not even 10 and yet he already gets excited for uniqueness of representations.
