Hints:

• No $ signs needed
• All formulas are rendered in display style
• Use op() custom operators (equivalent to LaTeX's \operatorname)
• Use mid(|) for conditional probability/expectation/etc., and use divides for divisibility (replacements for LaTeX's \mid)
• Use quad (mod n) for modulo (equivalent to LaTeX's \pmod)
• Harder formulas are worth more points
• Refer to the symbol reference to quickly look up unknown symbols
