  @Kevin-Li You have the right idea! The key is that the only time the amount of money changes is when Boris trades in a penny for 5 quarters... But, does this always mean that the amount of money is multiplied by 125? Here's an example: If I have two pennies and a nickel, that's 7 cents. If I trade in one penny for 5 quarters, i'd have one penny, one nickel, and five quarters, and that's 131 cents. Hm, my money didn't exactly get multiplied by 125. What exactly changed? Once you figure that out, you'll get the answer in no time!

  @TSS-Graviser It's \(-1\) because the point in question is point \(A,\) which is at \((-1,0).\) Why does \(e^{\pi i}\) give us this point? Because \(\pi\) corresponds to the angle \(180^{\circ}\) in the picture!

  @Kevin-Li We're no longer using the Discussions, as the forum is more full-featured and easier to use! Most of the useful Discussion posts were migrated over to the forums. Every video lesson should have a link to its own thread in the forum. Why is the forum better? You can search through topics You can type math You can edit posts Posts can be moved around You can search for most recent posts and more! Every Sunday, 7-9 pm (EST), we will hold office hours on the forum. Any questions asked during this time will be answered right away.
