It's not explained anywhere why $5.$6.6x.s4 becomes $56.64 and not $5.664 or $5664 or $566.4

Also, leading zeros don't make much sense (as alread reported earlier)

Hi, I have a couple of suggestions about this kata:

• Values like '$0967.24' doesn't make sense if we are talking about quantity, you should consider removing all leading 0s..
• There are ways of doing this that doesn't require importing 're', as my solution, but if you don't import it then you get an error of "global name 're' is not defined".
  Otherwise, a very fun kata, I liked it a lot.
  Regards!
