In other words, while a digit wheel holds 5 times as many values as a coin, it is only worth about 3\.32 times as much as a coin \(in terms of its ability to store data\)\. Why? Because it takes about 3\.32 coins to emulate a digit\-wheel\. What does that mean? Well, 3 coins is not enough to emulate a digit wheel \(3 give you only 8 possibilities\), 4 coins is more than enough \(4 give you 16 possibilities\)\. And 33 coins is not enough to emulate 10 digit wheels, but 34 coins are more than enough\. And 332 coins are not enough to emulate 100 digit wheels, but 333 coins are more than enough\.
This part is especially clear.
