If that's it, it's an old trick (older than programming) that you can convert each character to a numeric value[1], perform some calculations to transform them to something else, then back to characters again. It's a common technique for simple ciphers/encodings. If that's not it, it would really be helpful if you could explain what specifically about the math is throwing you.<div><br></div><div>One word of warning: while the Cuis Book is an easy read, it does have more math[2] than your typical pre-college level intro to programming book for some of the core game calculations which can't be avoided when you're dealing with thrust, projectiles and gravity. So unless you are prepared to just take some of the math parts coming up on faith and skip over exercises as needed, you may find some of the later sections frustrating. This level of math isn't needed to learn how to program, but is to implement the particular game the book covers. <div><br></div><div>[1] <a href="https://en.wikipedia.org/wiki/ASCII" target="_blank" rel="noreferrer nofollow noopener">https://en.wikipedia.org/wiki/ASCII</a></div></div><div><br></div><div>[2] My estimate just from a quick scan is intermediate Algebra with some basic Trigonometry.
