Use markdown for exercises, since it works fine out of the box.

 Bergamot, the interactive tool I've developed for doing exercises, supports
-customizing the notation for rules. Try changing the \(:\) symbol to
-the \(\sim\) symbol (denoted in latex as <code>\sim</code>).<br>

 To change the way that rules are rendered, click the "Presentation Rules"
 tab in the "Rules" section. There will be a lot there: I've added rules for
 pretty-printing a fair amount of the standard programming languages notation.

 One more thing. So far, we've only written down one claim: the value 1 is a number.

 Try writing the Bergamot rules that correspond to the inference rule for strings
 above. I've provided the rules for numbers; the rules for strings should be quite
-similar.<br>
-<br>
-In Bergamot, the claim that an expression <code>e</code> has type <code>t</code>
-is written as <code>type(e, t)</code>. A rule looks like <code>RuleName @ conclusion &lt;- premise1, premise2;</code>.
-Thus, the rule <pre><code>TNumber @ type(lit(?n), number) &lt;- num(?n);
-</code></pre>
-Has one premise, that the term \(n\) is a number, and the conclusion is that
-a number literal has type \(\text{number}\). The <code>num</code> condition
-is a Bergamot builtin, corresponding to our earlier notation of \(n \in \texttt{Num}\).
-It holds for all numbers: it's always true that <code>num(1)</code>, <code>num(2)</code>,
-etc. The equivalent builtin for something being a string is <code>str</code>.<br>
-<br>
+similar.

+In Bergamot, the claim that an expression `e` has type `t`
+is written as `type(e, t)`. A rule looks like `RuleName @ conclusion <- premise1, premise2;`.
+Thus, the rule
+
+```
+TNumber @ type(lit(?n), number) <- num(?n);
+```
+
+Has one premise, that the term \\(n\\) is a number, and the conclusion is that

+etc. The equivalent builtin for something being a string is `str`.
+
 To edit the rules in Bergamot, click the "Editor" button in the "Rules"
 section. You will need to add two rules, just like we did for numbers:
-a rule for string literals (something like \(\texttt{"Hello"} : \text{string}\),
+a rule for string literals (something like \\(\\texttt{\"Hello\"} : \\text{string}\\),
 but more general) and for adding two strings together. I suggest naming
-these two rules <code>TString</code> and <code>TPlusS</code> respectively.<br>
-<br>
+these two rules `TString` and `TPlusS` respectively.
+
 When you're done, you should be able to properly determine the types of
-expressions such as <code>"Hello"</code> and <code>"Hello" + "World"</code>.
+expressions such as `"Hello"` and `"Hello" + "World"`.

 These rules generally work in other languages. Things get more complicated in languages like Java and Rust,
