To type the sigma symbol (Σ for uppercase and σ for lowercase), you can use different methods depending on your device. On Windows, you can use the Alt code by holding the Alt key and typing 228 for uppercase (Σ) or 229 for lowercase (σ) on the numeric keypad. On Mac, you can type Option + W for σ and Option + Shift + W for Σ. In many word processors, you can also insert symbols from the menu or use Unicode: U+03A3 for Σ and U+03C3 for σ.
