Plain-text equations

Technical explanations
Unicode math signs are useful in prose, but complex expressions should stay in LaTeX, MathML, or an equation editor. For logic symbols, keep the surrounding label and detail notes aligned with the intended use.
Readable comparisons
Choose the simplest relation or operator that preserves meaning, especially in accessibility-sensitive UI and learning materials. For logic symbols, keep the surrounding label and detail notes aligned with the intended use.
