If, like me, you sometimes count using your fingers, odds are you can
count
up to 5 things on one hand (using 5 fingers). But that’s if you’re using
“unary” notation, whereby you only have a single digit (pun intended) at
your disposal, a finger, which you can think of as a 1. Binary, by contrast,
allows you to use two digits. O and 1. How high could you count on one
hand (with 5 fingers) using binary? Assume that a raised finger represents
a 1 and a lowered finger represents a 0.
