1. Minus Sign vs. Hyphen — Always use the proper minus sign (U+2212) for mathematical typesetting rather than the hyphen (-) to ensure correct visual appearance and spacing.

2. Multiplication Symbol — In formal mathematics, use × (\times) or · (\cdot) rather than the asterisk (*), which is primarily used in programming contexts.

3. Percent in LaTeX — The percent sign requires escaping as \% in LaTeX to prevent comment interpretation.

4. Large Operators — Summation ∑ and product ∏ symbols automatically adjust size in LaTeX based on display mode. Use \limits to control subscript/superscript placement.

5. Function Names — Function names like gcd, lcm, sgn should be set in upright roman type. LaTeX provides \gcd and \operatorname{} for custom functions.

6. Roots with Indices — For cube roots and higher, use \sqrt[n]{x} where n is the root index.
