How to Type Math Symbols
Windows: Use Alt codes for common symbols. Alt+251 = √, Alt+230 = µ. For complex symbols, use Character Map (search in Start menu) or copy from this page.
Mac: Many math symbols are accessible through Option key shortcuts. Option+5 = ∞, Option+B = ∫. The Character Viewer (Ctrl+Cmd+Space) lets you search for any symbol by name.
LaTeX: Mathematical documents use LaTeX notation: \sum = ∑, \int = ∫, \sqrt = √, \infty = ∞, \in = ∈, \subset = ⊂.
