    - Use $$ on separate lines for equations and solutions
    - Put each solution step on its own line in $$ $$
    - DO NOT use \\begin{{aligned}} or similar environments
-   - When writing questions involving currency expressed in dollars
-      * Use `\textdollar` for dollar signs (preferred method)
-      * Example: `\textdollar 1000` will display as $1000
-      * In math mode, still use `\textdollar`: `$\textdollar 85$`
-      * Never use `$` alone as it will be interpreted as math mode
+   - When writing questions involving currency expressed in dollars NEVER use the `$` symbol as it will be interepreted as math mode. ALWAYS write out the word dollars.
+      * Example: 1000 dollars
 5. Include a detailed solution
    - If the question involves geometry make sure to identify any general geometric formulas that apply, For example:
         * Areas/volumes of common shapes and solids
